Dan Koppen is carted off on opening night.FOXBOROUGH, Mass. -- The Patriots placed center Dan Koppen (leg) and defensive tackle Myron Pryor (shoulder) on injured reserve Wednesday and signed cornerback Phillip Adams and defensive lineman Landon Cohen to take their spots on the 53-man roster.
The 32-year-old Koppen fractured his left ankle late in the first half of New England's season-opening win in Miami. The 25-year-old Pryor, who missed the final seven games of last season due to injury, suffered a shoulder injury in the first half of Sunday's win over the San Diego Chargers.
Initial reports suggested Koppen might be able to return later in the season, but with injuries already mounting and Dan Connolly appearing steady in Koppen's place in Week 2, the team might not have been able to wait to see if Koppen could get back on the field.
Adams adds depth in a secondary where cornerbacks Ras-I Dowling (thigh) and Kyle Arrington (head) were both shaken up in Sunday's win over San Diego. Cohen has potential to fill Pryor's shoes as a rusher in sub packages.
