ALAMEDA, Calif. — The Oakland Raiders have signed quarterback Nathan Peterman to a reserve future contract.

Oakland added Peterman to the practice squad last month and then gave him a contract Tuesday to compete for a backup spot this off-season.

The Raiders also signed eight other players from their practice squad: receivers Saeed Blacknall and Rashard Davis; linebackers Cayson Collins and James Cowser; running backs James Butler and Ryan Yurachek; defensive back Makinton Dorleant; and tackle Jamar McGloster.

Oakland also signed punter Drew Kaser, who played 36 games for the Chargers from 2016-18.

Peterman was a fifth-round pick by Buffalo in 2017 and began this season as the starter for the Bills. He has 12 interceptions, three TD passes and a 32.5 career passer rating.
