LAKE FOREST, Ill. (AP) — The Chicago Bears have promoted cornerback Isaiah Frey and receiver Rashad Ross from the practice squad.

They also waived running back Shaun Draughn and receiver Chris Williams while terminating the contract of tight end Matthew Mulligan on Tuesday.

Frey spent last season as Chicago’s primary nickelback and could play a similar role with cornerback Charles Tillman suffering a season-ending arm injury at San Francisco on Sunday and rookie Kyle Fuller replacing him as a starter.

Ross spent most of last season on Tennessee’s and Kansas City’s practice squads after being signed by the Titans as an undrafted free agent out of Arizona State.
