Anderson exited Monday night's 25-6 loss to the New England Patriots with less than minute remaining after being hit and sacked by linebacker Kyle Van Noy.
The Bills remain without rookie quarterback Josh Allen, who head coach Sean McDermott said remains "week-to-week" but is "making good progress" in his recovery from an injury to the ulnar collateral ligament in his right (throwing) elbow.
Peterman has played in seven games (three starts) through two seasons, throwing nine interceptions and just three touchdowns on 81 attempts. He relieved Allen in Week 6 against the Houston Texans and gave Buffalo a brief lead before throwing a pick-six -- which proved to be the winning points for the Texans -- and another interception in the fourth quarter.
The team signed free agent Terrelle Pryor on Tuesday, but McDermott would not say if Pryor will be an option to play QB. McDermott added the team could bring in another veteran quarterback if Anderson is unable to clear protocol before Sunday's game.
Pryor, most recently a wide receiver for the New York Jets, has not played quarterback full-time since 2013, but he spent three years as a signal caller for the Oakland Raiders after playing quarterback in college at Ohio State.
The Jets cut Pryor earlier in October after just six games, as he battled a groin injury. The Bills are Pryor's fourth organization in three years, after he left the Cleveland Browns in 2017 for one year with the Washington Redskins.
To make room on the roster for Pryor, the Bills released cornerback Dontae Johnson, who played in just one game for the team after being signed Oct. 2.
