Patriots safety Patrick Chung underwent surgery on his right thumb, ESPN Boston reported Wednesday night. Thursday, CSNNE's Tom E. Curran confirmed that Chung will miss Sunday's game in Buffalo, and his status remains touch and go for the time being. Ian Rapoport of the Boston Herald first reported that Chung would be out.
The Bills rank first in the NFL in points scored, and Chung has been the most dependable member of the secondary so far this season for the Patriots. Losing him for the game will be a big blow to an already banged-up Pats secondary.
