Golden State Warriors star Draymond Green struck a Michigan State football player in the jaw during a weekend confrontation near campus, tried to apologize and then had to sit in jail for a while until he could sober up, according to a police report released on Wednesday.

Senior cornerback Jermaine Edmondson - who has received his release to transfer - claimed he was punched by Green early on Sunday outside a restaurant in East Lansing, though officers patroling the area said they saw or heard a "loud, open-handed slap."

Edmondson said it was his second confrontation with Green, a former Michigan State player, in two nights. He told police he and his girlfriend were choked on Friday night by men who were with Green at Rick's, a bar near campus.

He said he spotted Green the next night and tried to talk to him, according to the police report released to Associated Press.

"I walk over and I tell Draymond that last night wasn't cool," Edmondson, who is from Canton, Ohio, said in an e-mail to police.

"As he responded to me he began to poke me on my shoulder and I tell him that he doesn't need to put his hands on me, we can just talk. As I started to talk again, boom, I'm punched on my jaw."

He said he had a headache and pain in his neck and jaw.

Green was arrested and taken to the East Lansing jail where he had a blood-alcohol level of 0.10, police said.

He was released when sober.

Green said "he was sorry for slapping the subject and wanted to speak with him to make things right," officer Jeff Horn wrote.

On Wednesday night, Michigan State said in a statement that Edmondson was given his release and has decided to play his final college season elsewhere.

The announcement from the athletic department included no mention of the alleged altercation between Edmondson and Green.

"In discussions with Jermaine Edmondson following spring practice and in the weeks thereafter, it became clear that Jermaine wanted to play a larger role on the team," coach Mark Dantonio said in the statement.

"After consulting with him over the summer, he felt it was in his best interest to finish his playing career elsewhere."

Edmondson had 24 tackles last season. He was listed as a third stringer on Michigan State's spring depth chart.

If convicted of misdemeanor assault and battery, Green could face 93 days in jail, a $500 fine or both.

"My legal team is handling it. I think it will be resolved really quickly," Green said on Tuesday.
