49ers, Steelers Waive Injured Rookie Offensive Linemen

The Pittsburgh Steelers waived rookie offensive tackle Gareth Warren with an injury designation following a concussion sustained during their second preseason game against the Tampa Bay Buccaneers. Warren, an undrafted free agent from Lindenwood University, was signed after impressing during rookie minicamp and had seen playing time at both tackle positions, although his run blocking was less effective than his pass protection. The release was to make room for the signing of outside linebacker Kenny Willekes, who joined the team after an injury to Nick Herbig. Warren's injury occurred after attempting to recover a fumble, leading to his removal from the game and subsequent evaluation. If Warren clears waivers, he will revert to the Steelers’ injured reserve, potentially sidelining him for the 2025 season or leading to an injury settlement. Meanwhile, the San Francisco 49ers made roster moves by signing offensive lineman Michael Dunn, a former Cleveland Browns starter known for his run blocking, and wide receiver Malik Knowles, while waiving rookie running back Corey Kiner due to a significant ankle sprain and limited upside.
