PRO FOOTBALL

CLEVELAND (AP) With Johnny Manziel's professional career in doubt and his personal life crumbling, his father fears for the troubled quarterback's safety.

Manziel is facing a criminal investigation by police following allegations that he hit his former girlfriend last weekend in Texas. He was dropped by his agent Friday, was ordered this week to stay away from his ex for two years and will be released by the Cleveland Browns next month after two tumultuous seasons.

''I truly believe if they can't get him help, he won't live to see his 24th birthday,'' Paul Manziel told The Dallas Morning News.

Manziel's father said the family has made two unsuccessful attempts in the past week to get the player into a rehab clinic.

SAN FRANCISCO (AP) - NFL Commissioner Roger Goodell confirmed the Oakland Raiders would play the Houston Texans in Mexico City on Nov. 21, the first regular-season game in Mexico since 2005. The last regular-season NFL game in Mexico was in 2005, when 103,000 fans watched Arizona and San Francisco at Azteca Stadium. The NFL also has played seven preseason games there, none since 2001.

Goodell also said he is pushing to require the ejection of any player who is flagged for two personal fouls in a game. He has already recommended to the league's competition committee that it consider the rule change.

In December, Odell Beckham Jr., a receiver for the New York Giants, was allowed to stay in a game despite drawing three personal-foul penalties for unnecessary roughness, including one for a diving helmet-to-helmet hit on cornerback Josh Norman, whose Carolina Panthers will play in Sunday's Super Bowl. The two players engaged in all sorts of pro wrestling-style shenanigans throughout the game, and Beckham eventually was suspended for New York's next game.

TRENTON, N.J. (AP) - Former NFL star Plaxico Burress has five years to repay New Jersey $56,000 in back taxes and restitution or face going to jail, a judge said.

Burress, who received five years' probation, would face a 364-day jail sentence if he fails to make the payments in time.

MADISON, Wis. (AP) - Former Wisconsin and Denver Broncos running back Montee Ball was jailed on a felony battery charge after an apparent dispute with his girlfriend.

Police spokesman Joel DeSpain said officers were called to a downtown Madison hotel around 3:45 a.m. where a woman told police she and Ball were arguing when he threw her in the air. She said she landed on a table and cut her leg, requiring stitches. DeSpain said Ball told police he pushed the woman and she fell. DeSpain says Ball cooperated with officers.

COLLEGE BASKETBALL

LOUISVILLE, Ky. (AP) - The president of Louisville announced a one-year postseason ban for the Cardinals men's basketball team amid ongoing investigations into a sex scandal, a decision that stunned coach Rick Pitino.

President James Ramsey said at a news conference that an investigation revealed violations did occur when the school reviewed allegations by an escort that a former Louisville staffer paid her and other dancers to strip and have sex with recruits and players.

Ramsey said the ban is for all postseason tournaments, including the NCAA and the Atlantic Coast Conference tournaments. The president said he received the latest results of the investigation on Thursday, but noted the review of the allegations is continuing.

BASEBALL

CHICAGO (AP) - Chicago Cubs ace Jake Arrieta agreed to a $10.7 million, one-year contract, avoiding arbitration with the highest one-year deal for a pitcher with four years of major league service.

A person familiar with the negotiations disclosed the agreement and spoke to The Associated Press on condition of anonymity because the contract had not been announced by the team.

Arrieta, who turns 30 in March, had a breakout season last year, helping the Cubs to an NL wild card. The NL Cy Young Award winner finished with a 22-6 record and a 1.77 ERA, easily cruising past most of his previous career highs.

BOXING

DUBLIN (AP) - Gunmen disguised as police opened fire on boxing fans at a Dublin hotel, killing one man and wounding two others in an attack that could reflect tensions within Ireland's top cocaine-smuggling gang.

Fans attending the weigh-in ceremonies for a Dublin boxing event fled in terror as two gunmen wearing police uniforms opened fire inside the lobby of the Regency Hotel. Witnesses inside the ballroom hosting the ceremony saw two other men in the crowd, including one disguised as a woman, running away holding handguns. It wasn't clear whether they opened fire, were working as scouts for the other gunmen, or had come to the event armed and in disguise in anticipation of trouble from a rival gang.

Ko three-putted from 15 feet for bogey in frigid morning weather to complete the rain-delayed second round. In the afternoon, she made one birdie to get back to 7-under par through six holes. Ko was tied with Ha Na Jang, who played 24 holes.

USC President Max Nikias made the announcement, and also said Haden will start a one-year job guiding the renovation of the Coliseum after he retires.
