CLEVELAND (AP) Despite disturbing allegations that he struck his ex-girlfriend, troubled Browns quarterback Johnny Manziel has not been charged with a crime and two Texas police departments have closed their cases on a possible assault.

Manziel, who will be released by Cleveland next month, ending two turbulent NFL seasons, was being investigated for allegedly striking Colleen Crowley last weekend. She told police in Fort Worth that Manziel struck her ''several times'' and that the 2012 Heisman Trophy winner acted ''as if he were on some kind of drugs,'' but she maintained he was not intoxicated.

A police report released provided the first details of the altercation that took place between Manziel and Crowley, first at a hotel in Dallas and then as the couple drove back to her Fort Worth apartment. Both police departments investigated the incident but didn't charge Manziel.

WASHINGTON (AP) - Private investigators working for Peyton Manning visited the source of a report that he and other star athletes had obtained performance-enhancing drugs before the documentary aired late last year, according to a report from The Washington Post.

In December, Al Jazeera reported that an intern at an Indianapolis anti-aging clinic was secretly recorded suggesting that Manning's wife received deliveries of human growth hormone in 2011. Manning, then with the Colts, was rehabbing from neck surgeries.

The intern, Charles Sly, recanted his statements, which were recorded without his knowledge. He said they were fabricated in an attempt to impress a potential business partner. Manning angrily denounced the report, calling it ''completely fabricated, complete trash, garbage,'' and insisting he never took shortcuts in his return to football after missing 2011 with neck problems.

SAN FRANCISCO (AP) - The NFL is planning to play a regular-season game in Mexico City this year, with the Raiders hosting the Texans.

A person familiar with the decision told The Associated Press that the NFL will return to Mexico for the first time in 11 years. The person spoke on condition of anonymity because the NFL has not announced the game officially. Commissioner Roger Goodell is expected to do so in his Super Bowl news conference Friday.

A date for the game has not yet been determined; the NFL schedule comes out in the spring.

X GAMES

GREENVILLE, N.C. (AP) - Police say veteran X Games biker Dave Mirra has died in North Carolina. He was 41.

Greenville police said Mirra's body was found earlier in the day with an apparently self-inflicted gunshot wound. Authorities say they responded to an apparent suicide and discovered his body in a truck. They say he had been visiting friends in the area.

Mirra was an accomplished BMX rider and one of the most decorated athletes in X Games history, medaling every year from 1995 to 2008 and winning 14 gold medals. His one-time record of 24 career medals was broken in 2013 by Bob Burnquist.

OLYMPICS

RIO DE JANEIRO (AP) - Brazilian organizers have reiterated they have no intention of canceling the Rio de Janeiro Olympics because of the outbreak of the Zika virus, with Sports Minister George Hilton saying the topic ''is not in discussion.''

Hilton issued a statement saying he ''lamented material and opinions in the press'' speculating that South America's first Olympics might be called off. ''The Brazilian government is fully committed to ensure that the 2016 Rio games take place in an atmosphere of security and tranquility,'' Hilton wrote.

Brazil is the epicenter of an outbreak of the mosquito-borne Zika virus, which the World Health Organization has called ''an extraordinary event and public health threat.''

CAPE COD, Mass. (AP) - Jack Riley, the Army coach who in 1960 guided the U.S. to its first Olympic gold medal in hockey, has died. He was 95.

Riley died Wednesday on Cape Cod in Massachusetts, the U.S. Military Academy said Thursday. He regularly attended Army home games into his early 90s.

Jack Riley compiled a 542-343-20 record at West Point during a 36-year college coaching career that started in 1950, transforming the Black Knights into an Eastern power. He led the Black Knights to 29 winning seasons, including a school-record 28 victories during the 1983-84 season.

PRO BASKETBALL

SAN ANTONIO (AP) - Spurs guard Manu Ginobili is out for at least a month after surgery for a testicle injury he suffered during the team's win over New Orleans earlier this week.

Ginobili was injured with 2:26 remaining in the game Wednesday night. New Orleans forward Ryan Anderson had his back turned to Ginobili as he was working toward the basket when he spun quickly and struck the 38-year-old guard squarely in the groin with his right knee.

The team said Ginobili is out indefinitely, but won't return for at least a month.

NEW YORK (AP) - Stephen Curry will defend his title in the 3-point contest, Zach LaVine will try for another dunk championship and some All-Star big men will compete for the Skills Challenge crown in the All-Star Saturday events in Toronto on Feb. 13.

Sacramento's DeMarcus Cousins, New Orleans' Anthony Davis, Golden State's Draymond Green and Minnesota rookie Karl-Anthony Towns will take part in that event, which combines dribbling, passing and 3-point shooting and traditionally is made up of guards. Boston All-Star Isaiah Thomas, defending champion Patrick Beverley of Houston, the Lakers' Jordan Clarkson and CJ McCollum of Portland round out the field.

SOCCER

The U.S. Soccer Federation's original lawsuit against the union for its champion women's national team has been sealed after the governing body realized it had disclosed the home addresses and email accounts of many players.

A day after the original complaint was filed, the USSF filed a motion to seal it, saying ''private, personal contact information of individual members'' included in the exhibits ''is wholly irrelevant to the merits of the dispute.''

The clerk of the court was directed to seal the original complaint pending a decision on the motion by U.S. District Judge Sharon Johnson Coleman. A redacted version of the lawsuit, with player information blacked out, is now posted online.
