Vikings wide receiver Bernard Berrian finds himself in a difficult situation. He wants to get back on the field in order to start working with quarterback Brett Favre, but what Berrian doesn't want to do is aggravate a hamstring injury that has kept him out of action since the Vikings' preseason opener on Aug. 14 at Indianapolis. Berrian said Sunday that he has never had a hamstring injury before in his career, meaning a timetable for his return is going to have to be a play-it-by ear situation.
