Patriots SS Patrick Chung will miss Sunday's game against the Bills, according to PFW Patriots correspondent and Boston Herald writer Ian Rapoport.
Chung reportedly underwent surgery this week on his thumb and he did not practice on Thursday.
The third-year player has 14 tackles, one sack and one pass defensed in two games this season.
The way we see it
This is not a good development for a Patriots defense that has been far from stout this season. Chung is the leader of the safety group, that includes second-year player Sergio Brown and Josh Barrett, who is playing his first season with the Pats. Chung is good against the run and a playmaker, and the Bills can take advantage with Chung not on the field.
