Patriots cornerback Devin McCourty suffered a separated shoulder in the club's 37-16 win over the Jets on Sunday night, reported NFL Network's Albert Breer.
McCourty, who is the best cover corner in a New England secondary that has struggled most of the season, is expected to miss 2-3 weeks witha Grade 2 separation, Breer reported, citing a league source. The damage is to the AC joint, and there is no break or dislocation.
