The Steelers signed Walker off the practice squad to their active roster ahead of Sunday's game against the Browns.
EDGE Analysis
The 26-year-old was added to ensure depth at inside linebacker, as the team has already lost Kwon Alexander (Achilles), Cole Holcomb (knee) and Chapelle Russell (undisclosed) to injuries thus far. Walker's last in-game action came with the Falcons in 2022, when he started 12 games and tallied 107 total tackles.
