RIO DE JANEIRO -- Caster Semenya is the Olympic champion nearly seven years to the day after she arrived in track and field and sparked a controversy so complex and so sensitive, the sport is still struggling to deal with it.Against her wishes, the 25-year-old South African has become the face of the debate over whether women with much higher levels of testosterone than normal should be allowed to compete, unchecked, in top-level athletics. Because of Semenya, the IAAF put rules in place in 2011 to regulate womens testosterone levels, believing that high levels of the hormone gave them an unfair advantage. But the rules were dropped last year after a legal challenge by Indian sprinter Dutee Chand and were not in place at the Olympics.Semenya and Chand are not the only ones the rules were apparently lifted for. There are also believed to be other female athletes to compete at the Rio Games with a condition called hyperandrogenism, giving them abnormally high levels of naturally-occurring testosterone.Heres Semenyas story up to now, and an explanation of hyperandrogenism rules:---August, 2009:Semenya wins the 800-meter world title in Berlin as an 18-year-old newcomer, dominating a field packed full of the worlds best runners to triumph by a huge margin -- and stunning everyone watching. It was only half the story. Hours before the race, news leaked that the IAAF had conducted unspecified medical tests on the teenager. The tests -- likely to verify Semenyas sex and also to measure her testosterone levels -- led to her being declared ineligible to compete for 11 months. The IAAF has never commented publicly on the medical details of Semenyas case. It was also later revealed that South Africas track federation asked Semenya to have medical examinations.---March, 2010:Suspended -- apparently because of her high testosterone levels -- and frustrated with being forced to sit on the sidelines, Semenya turns up at a track meet in Stellenbosch, South Africa and demands to be allowed to run. Organizers, respecting the IAAF suspension, didnt let her. In a statement released through her lawyers, she then made clear her feelings:I have been subjected to unwarranted and invasive scrutiny of the most intimate and private details of my being, Semenya said. Some of the occurrences leading up to and immediately following the Berlin World Championships have infringed on not only my rights as an athlete but also my fundamental and human rights.It was one of few occasions where Semenya has spoken publicly about her situation.---July, 2010:In a brief, three-sentence statement, the IAAF announces that Semenya is cleared to compete again against other women, nearly a year after her gold at the worlds. The IAAF gave no details, only saying: The process initiated in 2009 in the case of Caster Semenya (RSA) has now been completed. The process the IAAF referred to is believed to be a course of testosterone-suppressing medication to reduce Semenyas hormone levels to within the normal female range. She kept her world championships gold medal and title.---September, 2011:Semenya, likely while taking the hormone medication, wins silver in the 800 meters at the world championships in Daegu, South Korea, behind Russias Mariya Savinova.---August, 2012:Semenya, a hero back home, carries South Africas flag in the opening ceremony at the London Olympics. On the track, she again finishes with silver behind Savinova, the Russian athlete now accused of doping. But the controversy over Semenya is stirred again when a television commentator suggests she may have lost intentionally to avoid the scrutiny that would come with a gold medal. Semenya dismisses the suggestion as nonsense.---2013-15:In terms of results on the track, its the toughest period in Semenyas career. Struggling with injury, and going through multiple coaching changes, Semenya slips down the pecking order in the 800. Its also speculated that the hormone medication is having an effect on her performances. In 2014, Semenyas best time was 2 minutes, 2.66 seconds, a huge seven seconds slower than the personal-best of 1:55.45 she ran in that breakthrough race at the 2009 world champs. She didnt even qualify for the final of the 2015 world championships a year ago, finishing last in her semifinal.---July, 2015:But a month before those 2015 worlds, a decision is made in sports highest court that has a huge bearing on Semenyas story. The Indian runner Chand opens up about her hyperandrogenism -- the only current athlete to do so -- and challenges the IAAF on rules that limit womens naturally-occurring testosterone. She won a temporary order, and the IAAF was told to drop the rules regulating testosterone until they can show how much of an advantage it gives to athletes.---July, 2016:Semenya, back to the dominating form of 2009 and easily the strongest 800 meter runner in the world again, runs a personal-best time of 1:55.33 at the Diamond League meet in Monaco. Its the fastest anywhere in the world for eight years. She goes even faster at the Rio Olympics.---Aug. 20, 2016:Semenya wins her first Olympic title, with her victory coming two hours after IAAF President Sebastian Coe, who was at the Olympic Stadium, says the international athletics body will go back to the Court of Arbitration for Sport in an attempt to have the testosterone-limiting rules reinstated.---Follow Gerald Imray on Twitter: https://twitter.com/GeraldImrayAPDave Krieg Jersey .

Aduriz headed home Markel Susaetas cross in the sixth minute to open the scoring at San Mames Stadium.

BOSTON -- Sean The Cannon Gannons claim to fame was a bloody, bare-knuckle fight he had with another mixed martial arts fighter. His day job as a Boston police officer hasnt been quite as action-packed.For the past decade, Gannon has been restricted to desk duty because police officials say his cognitive abilities have been affected by concussions he received during his fighting career. The city says public safety could be jeopardized if Gannon is allowed to work as an armed street cop.Gannon, however, insists he can fully perform all the tasks of his job as a police officer and has been cleared for duty by numerous doctors. Next week, the Massachusetts top court will be asked to decide whether his lawsuit against the city can proceed to trial. Oral arguments are scheduled for Dec. 8.Gannon began his career as a Boston police officer in 1996. In his spare time, he practiced martial arts -- including judo, aikido and jiujitsu -- and in 2002 he began to compete as an amateur mixed martial arts fighter.Gannon gained notoriety on social media in 2004 when he beat well-known fighter Kevin Kimbo Slice Ferguson in an unsanctioned fight. A 10-minute video of the brawl was widely distributed online.Gannons lawyers say he received two concussions during his career, both in 2004, and stopped fighting in 2005.In 2006, Gannon was placed on desk duty after he didnt report to work one day and the police department learned that he had a concussive syndrome from his fighting, as well as a diagnosis of sleep apnea.Gannon sued the city in 2012.A Superior Court judge found that the city had articulated a legitimate nondiscriminatory reason for assigning Gannon to desk duty, specifically its concern that his loss of cognitive function and memory impairs his ability to perform essential tasks of his job, including responding in an emergency and using the needed judgment in high-pressure situatiions.ddddddddddddGannon is appealing the judges ruling dismissing his disability discrimination claims and is asking the Supreme Judicial Court to allow a jury to decide his case.The citys lawyers say neuropsychological tests showed Gannon, now 46, had slow responses and memory issues, and was prone to errors. They argue that he cannot perform the job of an armed police officer.It is beyond dispute that a police officer must be able to respond properly on a split second basis to real or perceived threats, attorney Nicole Taub argued in a legal brief.But Gannons lawyers say their own experts used real world police scenario testing and found that he could fully perform the duties of his job.Here, the City has never tested Gannon in any shoot/dont shoot scenarios or simulated exercises that would gauge his ability to think quickly, react under pressure, and adapt to changing conditions. By contrast, whenever Gannon has undergone such testing on his own initiative, he has performed well, his lawyers argued in their brief.Gannon declined to comment. Attorney Adelaide Pagano told The Associated Press that Gannon has shown he is more than capable of performing the essential functions of the job of a police officer safely. She called the departments decision to keep him on desk duty obstinate and disgraceful.In a recent interview with MixedMartialArts.com, Gannon said he believes the department has retained a battery of medical experts to try to show he cant do his job, but he has numerous experts who say he can.If one doctor says youll never run again, and another doctor says you will, and then you run in five touchdowns in the pre-season, and another three in real games, its safe to say the doctor that said you would never run again is wrong, he said.
