The Seahawks make roster moves ahead of the Week 6 game vs. the 49ers

Young, a fourth-round pick in last year's draft, appeared in 16 games last season with one start, recording 18 tackles, one tackle for loss, one pass defensed and one quarterback hit.

Nwosu is going on injured reserve after suffering a thigh injury in last weekend's game. It was his first game since missing the previous four games with a knee injury, and the final 11 games of last season with a pectoral injury, a tough run of injury luck for a player who had missed a prior pectoral injury. Three games into his first five-plus season.

“Unfortunately, we're going to put Chenna on IR,” Seahawks coach Mike McDonald said Wednesday. “The timeline, we're not sure, but we think there's a really good chance to get him back by the end of the season. We're with him right now, he needs our support. The guy's been through a tough time, and he's going to work his tail off. , but it's unfortunate for him that we're leaning as a team, he's a leader of our defense and our football team to come back and be healthy and fresh for a late season run.”

Okada's elevation gives the Seahawks depth at safety with starter Julian Love listed as questionable for the game with a hamstring injury. McDonald said Wednesday that Love will be a game-day decision. Sheriff, an undrafted rookie out of South Alabama, will make his Seahawks debut when activated for the game. Sheriff was a standout for the Seahawks in the preseason, but was claimed by Carolina after the Seahawks waived him as part of a 53-player cutdown. After Carolina waived Sheriff last month, the Seahawks quickly signed him to their practice squad.

Sheriff Naosu is out and Boy Maffey and Derrick Hall are both listed as questionable, giving the Seahawks additional edge depth, though McDonald said those two are expected to be available.
