LONDON (AP) In a major doping crackdown stretching back eight years, 31 athletes in six sports could be barred from competing in the Olympics after they were caught in retesting of drug samples from the 2008 Beijing Games, and other positive cases could emerge from the 2012 London Games.
The International Olympic Committee opened disciplinary proceedings Tuesday against the 31 unidentified athletes from 12 countries who competed in Beijing and were planning to take part in the Rio de Janeiro Games in August.
The IOC said it also planned to reanalyze drug tests from the 2014 Sochi Winter Games after allegations samples were tampered with as part of a state-sponsored Russian doping program.

The positive cases from Beijing emerged from the recent retesting of 454 doping samples with ''the very latest scientific analysis methods,'' the IOC said.
The Olympic body stores samples for 10 years to allow for retesting with improved techniques, with athletes caught facing retroactive disqualification and loss of any medals.
NEW YORK (AP) - U.S. prosecutors are investigating claims that dozens of top Russian athletes participated in a sophisticated state-sponsored doping program, The New York Times reported.
Two unidentified sources confirmed the investigation to the Times, requesting anonymity because they did not have authorization to speak publicly.
The probe, launched by the U.S. Attorney's office for the Eastern District of New York, is looking at athletes, Russian government officials, anti-doping authorities and people who may have benefited from the doping scheme, the Times reported.
A law enforcement official with knowledge of the investigation confirmed to The Associated Press there is an FBI inquiry related the Russian doping scandal, but offered no details.
The official wasn't authorized to discuss the investigation and spoke on condition of anonymity. The investigators are from same team handling the FIFA probe, which is also being overseen by prosecutors in Brooklyn.
GENEVA (AP) - The World Health Organization's chief says the agency is increasingly concerned about the Zika virus, even though it does not recommend canceling or postponing the Rio de Janeiro Summer Olympics in hard-hit Brazil.
''The more we learn about Zika, the more worried we get about it,'' Dr. Margaret Chan said in a briefing Tuesday in Geneva, saying she herself would be going to the Rio Games.
Chan noted that although Zika has been around for decades, it is only recently that the virus has been proven to cause severe birth defects and neurological problems - including in newborn children.
She reiterated the U.N. health agency's advice that pregnant women should not travel to Brazil, which has by far the biggest number of Zika cases.
She said the agency was recommending that both Olympic athletes and travelers to Rio take measures to prevent being bitten by the mosquitoes that spread Zika. Still, she didn't see a reason why the games - which are expected to draw about 500,000 people to Brazil - should be moved.
TORONTO (AP) - Texas second baseman Rougned Odor was suspended for eight games and fined $5,000 by Major League Baseball for punching Toronto's Jose Bautista on the jaw.
Major League Baseball disciplined 14 players and staff for their roles during Sunday's brawl at Arlington, Texas.
Blue Jays pitcher Jesse Chavez was suspended three games for hitting Prince Fielder with a pitch. Manager John Gibbons, who returned to the field for the fight following his ejection five innings earlier, was penalized three games for inciting additional fighting.
Bautista, who made a hard takeout slide at second base on Odor, was suspended for one game by MLB senior vice president Joe Garagiola Jr. for his actions and postgame comments.
Rangers shortstop Elvis Andrus was suspended for one game for aggressive actions and Blue Jays first base coach Tim Leiper for one game for returning to the dugout following his ejection.
ATLANTA (AP) - The Atlanta Braves fired manager Fredi Gonzalez, who couldn't survive the worst record in the majors.
Braves general manager John Coppolella confirmed the firing. This was Gonzalez sixth season with the Braves, who are in the midst of a dismal stretch: They have lost two straight and eight of 10, have baseball's worst record at 9-29 and already are 13 1/2 games out of first place in the NL East.
Brian Snitker, who has been manager of the Braves' Triple-A Gwinnett team, will move up as interim manager. Snitker was Atlanta's third-base coach from 2006 to 2013, also following Gonzalez in that role when Gonzalez was named manager of the Marlins.
Snitker also had two stints with Atlanta as the bullpen coach in 1985 and from 1988 to 1990.
The Braves also fired bench coach Carlos Tosca. Gwinnett pitching coach Marty Reed has joined the club as bullpen coach. Terry Pendleton will move from first base coach to bench coach and Eddie Perez will move from bullpen coach to first base coach.
NEW YORK (AP) - The Philadelphia 76ers won the NBA draft lottery and will have the No. 1 pick in June.
The Los Angeles Lakers finished second but also felt like winners, as they would have dealt their pick to Philadelphia had they fallen out of the top three.
The Boston Celtics, with a pick dealt to them by the Brooklyn Nets, remained in the No. 3 slot.
Nobody moved up in the lottery, which sets the top three picks. The remainder of the 14 teams are slotted in the inverse order of their won-loss record.
The 76ers finished 10-72, just off the worst record in the history of the 82-game schedule, and had a 26.9 percent chance of landing the No. 1 pick (their own 25 percent chance, and Sacramento's 1.9 percent chance, since the 76ers had the right to swap picks with the Kings from a previous trade).
Chris Weidman has withdrawn from his UFC 199 middleweight championship bout because of an undisclosed injury, according to a person with knowledge of the situation.
The person spoke to The Associated Press on condition of anonymity because no official announcement has been made.
Weidman was scheduled to fight Luke Rockhold in a rematch from their December 2015 bout at UFC 194. Rockhold (15-2) defeated Weidman (13-1) by TKO to win the UFC middleweight title.
The UFC will now likely explore a replacement opponent for a bout that was scheduled to headline the June 4 card at The Forum in California.
Rockhold has won five straight bouts.
Weidman's withdrawal was first reported by Fox Sports.
