The Seahawks added linebacker Tanner Muse to the 53-man roster on Wednesday, signing the former third-round pick off of their practice squad.
He replaced defensive back Gavin Heslop on the roster, with Heslop going on injured reserve after breaking his tibia and fibula in Sunday's win over the Texans. The Seahawks also added safety Josh Jones to their practice squad.
Muse, who was drafted by the Raiders last year, missed his rookie season with a toe injury, then signed to Seattle's practice squad in September after being waived by Las Vegas. A first-team All-ACC selection as a senior, Muse was a two-time national champion at Clemson and a team captain.
In addition to providing linebacker depth, Muse figures to take on a big role on special teams. Muse has been elevated from the practice squad twice this season, and in those games he played 65 percent of Seattle's special teams snaps against Jacksonville, and 78 percent against Green Bay.
Jones, a second-round pick out of NC State in the 2017 draft, spent his first two seasons in Green Bay, starting seven games as a rookie, and has also played for Dallas, Jacksonville and most recently the Colts, appearing in a total of 54 games, starting 25. Last season Jones started 13 games for Jacksonville, recording a career-best 83 tackles and one interception.
