Holcomb (knee) was placed on the reserve/PUP list Tuesday.
Holcomb is still working his way back from the season-ending knee injury he suffered in Week 9 of the 2023 season and he'll be forced to sit out at least the first four weeks of 2024. Once healthy, the 28-year-old is expected to operate as Pittsburgh's third option at interior linebacker behind Patrick Queen and Elandon Roberts.
