Greenlaw (hamstring) was a full participant at practice Monday, Nick Wagoner of ESPN.com reports.
The 26-year-old linebacker had been sidelined by a hamstring issue since Aug. 10, but it now appears he's set up to play Week 1 at Pittsburgh. After recording a career-high 127 tackles in 2022, he'll likely be busy right off the bat in 2023 against a Steelers ground attack helmed by Najee Harris.
