Greenlaw (Achilles) is expected to be activated from the reserve/PUP list and suit up Thursday night for San Francisco's home matchup against the Rams, Jeremy Fowler of ESPN.com reports.
Greenlaw is expected to make his 2024 debut on Thursday Night Football, but the 49ers will first have to officially activate him to the 53-man roster. The veteran linebacker was designated to resume practicing Nov. 27 and managed to resume full participation levels Wednesday. Greenlaw is working his way back from a left Achilles tear sustained in Super Bowl LVIII against the Chiefs.
