The Seahawks have promoted linebacker Nick Moody from the practice squad to the 53-man roster, and have made the Crezdon Butler signing official.
Moody fills a role as depth behind Bobby Wagner, who injured his pectoral muscle in Sunday's game. Wagner's status for this week's matchup with the Panthers is a question mark, and Pete Carroll indicated today that while Wagner feels better than he did on Sunday, he'll be day-to-day and will likely be a game-time decision.
Either way, Moody likely figures to play some special teams at least.
When the Niners drafted Moody in the sixth round out of Florida State in 2013, Jim Harbaugh told reporters that he's "one of the best we've seen [in special teams] in college football." He played safety and linebacker for the Sooners and was known for his hard hitting style.
Butler provides depth for the cornerback spot, which is experiencing some injuries as well. Marcus Burley and Tye Smith are both dealing with injuries and may not be available for next week's game. Butler was a fifth-round pick by the Steelers in 2010 and has bounced around the NFL since then, with stints with the Steelers, Cardinals, Washington, Bills, Chargers, Buccaneers and Lions. He played in 14 games for the Bucs in 2014 -- starting three -- and will add some depth for Seattle, who is now without Simon, plus Tye Smith and Marcus Burley for the time being as they deal with injuries.
Butler is 6'0, 183, and his measureables out of Clemson (where he was Byron Maxwell's teammate) are solid: 4.49 forty, 39.5-inch vert, 10-foot-1-inch broad, 7.08 three-cone.
