The Facts: Via multiple reports, Kolb injured himself while walking to a field on Saturday. Per Mark Gaughan of the Buffalo News, Kolb slipped on a rubber mat while walking from one field to the other. Via Sal Capaccio, trainers looked at Kolb’s knee. Per Capaccio, Kolb was “visibly upset” as he headed to the locker room with his pads off.
Diehards Line:HC Doug Marrone told reporters after practice that Kolb “bumped his knee and he’s day to day. ...” We'll see about that. As PFT's Mike Florio notes, the injury comes a day after Marrone told reporters that the team is “very, very pleased” with rookie QB EJ Manuel’s progress. Sounds like Manuel will get further opportunities to please Marrone in coming days.
