The Bills signed AJ McCarron on Wednesday, which immediately pushes Nathan Peterman down the depth chart.
The Bills traded Nathan Peterman's teammate, Tyrod Taylor, to the Browns on Friday in exchange for a third-round pick.
Nathan Peterman came into Sunday's 10-3 AFC wild-card loss to the Jaguars with 1:16 remaining in the fourth quarter in place of Tyrod Taylor (concussion) and went 1-for-3 for 14 yards with an interception. He also rushed once for four yards and recovered his own fumble.
Nathan Peterman was cleared from the league's concussion protocol Monday, Mike Rodak of ESPN.com reports.
