Grace joined Atlanta's practice squad on Thursday, D. Orlando Ledbetter of The Atlanta Journal-Constitution reports. In a corresponding move, the team waived linebacker Richie Brown.
The second-year man returns to Atlanta, where played five games and served as a member of the team's practice squad in 2017. More recently Grace had stints with the Browns and Seahawks, who waived the 24-year-old linebacker earlier this week. He'll provide developmental depth for a linebacker corps that has been depleted by an early-season injury to Deion Jones (foot).
Grace was waived by the Browns on Sunday, Pat McManamon of ESPN reports.
Grace spent most of the offseason with the Browns but evidently was unable to distinguish himself at linebacker. He'll now head back to the free-agent market if he passes through waivers unclaimed.
Grace split his rookie campaign between the Colts and Falcons, finishing with just three total tackles across 11 games. After the linebacker was waived by Indianapolis earlier in the week, the Browns have elected to kick the tires, though Grace will need a strong showing in training camp to have a realistic shot at making the 53-man roster.
