Denver Broncos outside linebacker Randy Gregory will miss at least four weeks due to a knee injury.
The club placed the pass rusher on injured reserve on Tuesday, forcing him out for at least the next four games.
NFL Network Insider Tom Pelissero reported on Monday that Gregory will undergo arthroscopic surgery to trim the meniscus in his injured knee. The good news is that Gregory's ACL is intact.
Tuesday's move to place the edge rusher on IR firms up the timeline. Gregory is eligible to return in Week 10 after the Broncos' bye.
