LA UNION, Colombia (AP) Colombian authorities searched for answers into the crash of a chartered airliner that slammed into the Andes mountains while transporting a Brazilian soccer team whose Cinderella story had won it a spot in the finals of one of South America's most prestigious regional tournaments. All but six of the 77 people on board were killed.

The British Aerospace 146 short-haul plane declared an emergency and lost radar contact just before 10 p.m. Monday (0300 GMT Tuesday), according to Colombia's aviation agency. It said the plane's black boxes had been recovered and were being analyzed.

The aircraft, which departed from Santa Cruz, Bolivia, was carrying the Chapecoense soccer team from southern Brazil for Wednesday's first leg of the two-game Copa Sudamericana final against Atletico Nacional of Medellin. Twenty-one Brazilian journalists were also on board the flight.

Colombian officials initially said the plane suffered an electrical failure but there was also heavy rainfall at the time of the crash. Authorities also said they were not ruling out the possibility, relayed to rescuers by a surviving flight attendant, that the plane ran out of fuel minutes before its scheduled landing at Jose Maria Cordova airport outside Medellin.

LONDON (AP) - British police investigating sexual abuse in soccer have received calls from 250 people, the government announced, as FIFA said the high-profile scandal could lead to offenses by youth development coaches being exposed worldwide.

In a day of developments, Chelsea also opened an investigation into an employee from the 1970s who is now dead, while the English Football Association acknowledged it was braced for compensation claims.

Former professionals have been speaking publicly for the first time over the last two weeks about the ordeals they went through as youngsters. Some of the victims previously gave evidence to convict offenders without being named but new allegations are also being reported.

Police Scotland joined seven forces in England by confirming it was looking into abuse claims.

FIFA does not believe Britain is the only country where the game has been exploited by pedophiles, and world soccer's governing body is ready to offer ''psychological support'' to victims.

COLLEGE FOOTBALL

UNDATED (AP) - Oregon has fired coach Mark Helfrich after a disappointing 4-8 season, and just two years after getting the Ducks within a victory of the program's first national championship.

Helfrich was head coach of the Ducks for four seasons, leading the team to the first College Football Playoff championship game after the 2014 season. But Oregon faltered this year with a five-game losing streak, and finished at the bottom of the Pac-12 North with just two conference wins.

After taking over when Chip Kelly left in 2013, Helfrich went 37-16. He had an $11.6 million buyout on his contract with the Ducks.

Helfrich met with athletic director Rob Mullens on Tuesday night and was told was being dismissed. Helfrich issued a statement saying he was honored to have served at Oregon.

UNDATED (AP) - Ohio State held firm at second in the College Football Playoff rankings, putting the Buckeyes in position to become the first team to be selected to the final four without winning its conference.

Alabama was No. 1 in the second-to-last rankings, followed by Ohio State, Clemson and Washington. The Crimson Tide, Tigers and Huskies all play conference championship games this weekend and presumably would be in good shape to make the playoff if they win. The final rankings and playoff pairings will be released Sunday.

Michigan dropped to five after losing to Ohio State. Wisconsin was sixth and Penn State was seventh. The Badgers and Nittany Lions will play for the Big Ten title in Indianapolis on Saturday.

PRO FOOTBALL

LOS ANGELES (AP) - Former NFL star Darren Sharper was sentenced to a 20-year prison term, ending a tour of shame and punishment in the courthouse where he first admitted drugging and raping women in four states.

Los Angeles Superior Court Judge Michael Pastor denounced Sharper's ''horrible conduct'' and ''disgraceful abuse of trust'' during the hearing that concluded prosecutions that unmasked the popular former all-pro safety and Super Bowl champ as a serial rapist.

Under the terms of a plea deal negotiated with prosecutors in four states, Sharper will be eligible for parole in about eight years because California law requires he serve half his sentence and he has already been behind bars more than two years since his arrest.

But he will probably serve more time if an appeals court upholds an 18-year prison sentence handed down by a New Orleans federal judge who rejected the deal as too lenient. Sharper has appealed that harsher sentence.
