The NFL is investigating whether Cleveland Browns wide receiver Braylon Edwards violated the league's conduct policy following accusations he assaulted a man outside a nightclub.

Edwards allegedly punched promoter Edward Givens, a friend of NBA superstar LeBron James, early Monday morning following an argument in downtown Cleveland.
``We are looking into it,'' league spokesman Greg Aiello said Tuesday in an e-mail. ``It is premature to speculate about potential discipline.''
Although Edwards has not been charged with a crime, the league's conduct policy states that discipline may be imposed for ``the use or threat of violence.''
James called Edwards ``childish'' for punching his friend.

Oddsmakers from online sports book have made the Browns 6-point underdogs on Sunday against the Bills. The over/under for that game has been established at 40.
