Overview
- NFL insider Aaron Wilson reported the Steelers signed Marte Mapu to the practice squad on Monday.
- Mapu fills a practice-squad vacancy created after the team traded Joey Porter Jr. and promoted Doneiko Slaughter to the active roster.
- Mapu was a 2023 third-round pick and has 44 NFL appearances with 10 starts, including nine starts in the 2024 season when he had 46 tackles, six pass defenses and three forced fumbles.
- Pittsburgh hosted multiple tryouts during a mini-bye that included Mapu and former Jaguars third-rounder Chad Muma as the team looked for linebacker depth after missed tackles in a recent loss.
- The signing is a depth-and-evaluation move that gives the Steelers a player with special-teams experience and position flexibility who can be elevated for short-term game-day help.
