Strong safety Kam Chancellor has been ruled out for Monday night's game against the Atlanta Falcons, which means the Seahawks will be without two Pro Bowl starters in their secondary with cornerback Richard Sherman going on injured reserve earlier this week.

Seahawks coach Pete Carroll said the team is still gathering information on Chancellor, who injured his neck in Thursday's win at Arizona, before making any prognosis beyond this week's game.

"We're still looking at what our options are, and we'll continue to do that and evaluate what's going on," Carroll said. "We're working very closely with him on that… We'll just wait and see. We're working through it and we've met on it, we're hanging together and just trying to talk our way through it and not have to do anything any faster than we have to. We'll just wait and see."

Yet even with so many key defensive players out for this game—Pro Bowl defensive end Cliff Avril is also on injured reserve, and starting strongside linebacker Michael Wilhoite is also out this week with a calf injury—Carroll is confident about his team's ability to maintain a high level of play due to the depth the team has on defense and in its secondary in particular.

"We couldn't be more fortunate in the guys who get to step up for those guys," Carroll said. "You can't replace either (Sherman or Chancellor) directly. They've been here a long time, they've done so much, they stand for so much. Yet we have guys who are coming in—Bradley McDougald has played excellent football, he's a first-flight starter in the NFL, so we're lucky to have him jump in; then Jeremy Lane was a starter for us this year, and (Shaquill Griffin) has taken over as a starter on the right side. To be able to answer Sherm going down with Jeremy coming back and also bringing in (Byron Maxwell), we just feel fortunate that we've been able to respond in this manner. A lot of teams aren't able to do it like that. So we'll see how it goes, but we expect those guys to play really well.

"The true test is when we come back and play a couple more games and see how we're doing and see how it all holds together like we want, but we couldn't be happier with the guys who are jumping in there. These guys are ready to play football, they've been playing, they know how to play the game, and the experience they bring really helps smooth the transition."

In other injury news, left tackle Duane Brown (ankle) and defensive tackle Jarran Reed (hamstring) are both expected to be game-day decisions.

"Both of those guys are questionable, and we're going to right up to game-time with both those guys," Carroll said. "Jarran got pretty good work today, a little bit more than Duane did at this time. We're just kind of waiting through the entire expanse of this break here to see if we can max it for Duane."

Left guard Luke Joeckel will be out again this week as he comes back from knee surgery, but has a good chance to return to practice next week.

"He's real close," Carroll said. "He's working hard, he's running, he's doing all kinds of stuff, but we want to make sure that when he gets back, he stays back… I really think he will (practice next week). He worked really hard this week in prep, but he was just a little sore coming out of the work. As we often tell you, it's the next day that tells you something, so it just depends on how he responds. He's really close to going, he feels like he could play, but we're not sure what the response is going to be yet, and we just don't want to burden him into the next week and next week. So we're going to hold off and be patient just a bit longer and make sure that when he gets back, he stays back."

Carroll also confirmed that running back Eddie Lacy is able to play after missing last week's game with a groin injury: "Eddie's ready to go. He practiced all week and is in good shape. He looks good."

For the Falcons, the most notable name on the injury list is starting running back Devonta Freeman, who has been ruled out due to a concussion.
