Lions activate LB Steve Longa to the 53-man roster. To make room, the team cut safety Marcus Gilchrist, who was signed this week after the team traded Quandre Diggs to Seattle. Longa was one of Detroit’s top special teams players in 2017 before tearing his ACL that cost him 2018. He’s about 14 months out of surgery at this point.
