Carter (concussion) didn't practice Wednesday, but the Jets are optimistic he could play this Sunday against the Bills, Rich Cimini of ESPN.com reports.
Brian Costello of the New York Post reports that Carter did some work on a side field Wednesday, suggesting he's already making progress through the NFL concussion protocol. The rookie got off to fast start in Sunday's 28-24 loss to Tampa Bay, ripping off a 50-yard run in the first quarter before a concussion forced him out of the game. Head Robert Saleh said Wednesday that Carter is "progressing well" and is expected back soon.
