Two Thursdays ago, Browns rookie running back James Davis aggravated a shoulder injury and suffered a torn labrum that now will require surgery in Alabama this week with Dr. James Andrews.
How Davis was injured is the question swirling around the league.
Two witnesses to the incident from within the Browns organization said Davis injured his shoulder in a post-practice drill in which he was not wearing pads and the linebacker that plowed into him was. Three other NFL sources corroborated the witnesses' account.
A Browns spokesman said Saturday it is not true.
Once he denied the events, the sources were contacted Saturday for a second time -- some for a third or fourth -- and asked about the incident again.
Each repeated the same details. Davis was injured during a pass blocking drill in what Cleveland calls a post-practice "opportunity period" when a Browns linebacker in pads "got frisky" and "trucked" Davis, who was not in pads.
The NFL has been aware of this incident and has been looking into it, a league spokesman said this weekend.
