The Pittsburgh Steelers placed defensive tackle Sebastian Joseph-Day on injured reserve Thursday.
Joseph-Day did not participate in Wednesday’s practice due to a triceps injury. He will miss at least the next four games on IR.
Signed as an unrestricted free agent in the offseason, Joseph-Day has totaled 10 tackles and a fumble recovery in six games this season.
A Super Bowl champion with the Los Angeles Rams, Joseph-Day has totaled 324 tackles, 15.5 sacks and three fumble recoveries in 111 games (90 starts).
Joseph-Day, 31, has played with the Rams (2019-21), Los Angeles Chargers (2022-23), San Francisco 49ers (2023), Tennessee Titans (2024-25) and Steelers since being selected by the Rams in the sixth round of the 2018 NFL Draft.
