NFL free agent quarterback Johnny Manziel posted bond Wednesday in his misdemeanor assault case after turning himself in to police in a Dallas suburb. The former Cleveland Browns player and Texas A&M University star has been accused of beating in January his then-girlfriend Colleen Crowley, a Houston-born model.

TMZ reported Manziel was at the headquarters of the Highland Park Department of Public Safety only for a short time and was “polite and cooperative” before posting $1,500 bail. “Johnny Football” could face as long as a year in jail in the event he is found guilty.

Manziel is scheduled to appear in court Thursday. The alleged altercation happened in Avon, Ohio, but the football player was given the option to turn himself in to any police department in Texas after a Dallas grand jury indicted him on a domestic violence charge last month.

Manziel’s former coach at Texas A&M, Kevin Sumlin, told 98.7-FM radio in Phoenix that Manziel hasn’t responded to Sumlin’s effort to reach out to him.

“I had texted him a couple of times and given him a call, but haven’t got a return back,” Sumlin said. “So from that standpoint, it’s a little unnerving.”

The 2012 Heisman Trophy winner was cut by the Browns in March after the allegation of domestic violence against Crowley. However, the team has had other issues with Manziel, who underwent alcohol and drug treatment in Pennsylvania last year, as CNN reported.

“I owe private apologies to a lot of people that I disappointed, but a very public one to the Browns organization and the fans that I let down,” Manziel said in a statement after leaving a rehab center in April 2015.

Crowley has claimed Manziel struck her numerous times during a domestic altercation Jan. 30. She also has claimed the athlete dragged her by the hair and threatened to kill both of them.
