Despite being down a few playmakers in Buffalo, the Seahawks will see some welcome faces on defense.

All-pro safety Jamal Adams will return to the field Sunday, marking his first appearance since he was sidelined by a groin injury in Week 3. According to Seahawks head coach Pete Carroll, Adams will not be subjected to load management or any type of restrictions in his first game back. "We won't limit him at all. He took everything this week," Carroll said Friday. "He reported coming off the rehab really fit, so he looked great this week. He was flying. I don't see any reason to restrict him at all."

Adams had 21 tackles and two sacks in his first two full games prior to injury. He also brings an undeniable energy to the field, according to his head coach. "He's just a fireball. He's got so much juice to him," Carroll explained. "He plays at such a high level, and it translates to other guys in giving them confidence, and he'll pick guys up after good plays, after bad plays, he's just got such a positive effect that he's a big factor. He's a big factor."

Pro-Bowl defensive end Carlos Dunlap II will also make his highly-anticipated debut for the Seahawks Sunday, after being acquired in a late October trade with the Bengals. "Carlos has been a very, very consistent player for a long time," Carroll said, back on October 28. "He's always been fast, always been athletic, he still moves his feet well and gets off the rock and knows exactly how to play the spot that we want to play him in."

The 31-year old Dunlap II, a former second-round pick by the Bengals, built an impressive stat line over his 11-year career. He recorded 82.5 sacks, 490 tackles, 20 forced fumbles, nine fumble recoveries, 60 passes defensed, and two interceptions, both of which he returned for touchdowns.

Dunlap adds experience and depth to the Seahawks pass rush, which has struggled this season, but recorded three sacks last weekend against San Francisco. The addition of 6-foot-6, 285-pound Dunlap in the trenches could help the Seahawks build on their production from last week. Will the veteran experience a learning curve with a new system? Carroll is not worried. "Carlos had a really, really complete week," he explained Friday. "He was ready to go, right at the beginning of the first day and the walkthrough, and he had already started up over the weekend and stuff came real easy to him. So he was able to go out and play really clean. That's your concern – is he confused, does it slow him down, the new system and all? But he's played enough ball and he understands the principles and they do fit the way he's liked to play in the past. And so, the transition was nothing. It was seamless."

Defensive end Rasheem Green was activated from injured reserve this week and will be good to go Sunday, adding more depth to the defensive line. The young pass-rusher has been sidelined with a stinger since the Hawks season-opener. 

Cornerback DJ Reed, RB Travis Homer, CB Ryan Neal and WR David Moore are all active after being limited Friday. Rookie DeeJay Dallas and Homer will see plenty of opportunities again in the backfield with Carson and Hyde out. RB Alex Collins will also be available after being elevated from the practice squad on Friday.
