Reed is slated to serve as the Ravens' No. 2 quarterback for Thursday night's game against Jacksonville.
Reed was signed to the 53-man roster off the practice squad Thursday. With both Lamar Jackson (thumb) and Tyler Huntley (toe) on injured reserve, Reed will back up Joe Fagnano in Week 9, with Kedon Slovis (coach's decision) inactive but available if needed as the emergency No. 3 quarterback.
