The Bengals have agreed to sign Wallace Gilberry, according to a source who spoke with Jim Owczarski of The Enquirer. The Bengals will have to make a corresponding move to carve out a spot for him on the 53-man roster. 
Gilberry auditioned for the Bengals during their bye week workouts and made a good impression on coaches. Fullback Marcel Reece, defensive tackle Jordan Hill, and tight end Justice Cunningham also showed their stuff for the Bengals on Wednesday.
Gilberry joined the Lions this offseason and was being used as a situational pass rusher. After four games, he was sidelined by an abdominal injury. Detroit subsequently placed him on IR before releasing him on Oct. 11. Before that, the 31-year-old played for the Bengals from 2012-15, starting in 19 games for the team and recording 16.5 of his 35.5 career sacks with Cincinnati.
