Sheard suffered the injury in the team's first preseason game. The pass-rusher's recovery timetable is 2-4 weeks, which should get him back on the field for the Pats' regular season opener versus the Arizona Cardinals.
If the recovery extends into the regular season, however, it will be another ding to New England's ability to disrupt the quarterback.
Other injuries we're tracking on Tuesday:
- Bills head coach Rex Ryan said defensive back Nickell Robey-Coleman has a quadriceps contusion, quarterback Cardale Jones has a sore shoulder and tackle Jordan Mills suffered a knee injury, but the staff doesn't know the extent of the injury yet. Ryan also said wideout Sammy Watkins (foot) is scheduled to play Friday versus Washington, but not much. Linebacker Manny Lawson will also play.
