The Steelers placed defense end Stephon Tuitt on the reserve/injured list after he suffered a pectoral injury in the first half of the team's 24-17 win over the Los Angeles Chargers.
Tuitt was having a strong season, tied for the team lead with 3 ½ sacks and six tackles for a loss. He also had six quarterback hits before suffering the injury.
Tuitt, who was selected by the Steelers in the second round of the 2014 NFL draft, has missed time during his career with injuries, including elbow injuries the past two seasons that forces him to miss a combine six games.
With a roster spot open the team signed defense end L.T. Walton.
Walton was selected by the Steelers in the sixth round of the 2015 NFL Draft. He played in four games in 2018, against Kansas City, Carolina, Jacksonville and Denver, recording a tackle and a pass defense. He was inactive for 12 games.
Walton has been used throughout his career mainly in a reserve role, playing in 36 games with four starts, all in the 2016 season. He has recorded 19 tackles, including 14 solo stops, three passes defensed, and two sacks during the 2017 season.
Walton signed with the Bills in June but was released prior to the start of the 2019 season.
The team also signed running back Tony Brooks-James and offensive lineman Christian DiLauro to the practice squad.
Brooks-James, who played at Oregon, signed with the Atlanta Falcons as an undrafted rookie free agent and spent time on their practice squad this year.
DiLauro played college football at Illinois and has spent time with the Cleveland Browns and San Francisco 49ers.
