The Seahawks will likely be without Earl Thomas for a second straight week, as the All-Pro free safety is listed as doubtful for Thursday night's game in Arizona with a hamstring injury. Seattle is, however, likely getting back another key defensive player, with defensive tackle Sheldon Richardson expected to return from the oblique injury that kept him out last week.
"Because of the severity of the strain, it has taken some time," Carroll said of Thomas, who injured his hamstring late in Seattle's Week 8 win over Houston. "We're not able to get him to practice yet."
Though Richardson is officially listed as questionable, Carroll said "It looks like it, we're counting on it," when asked if he would play.
Also questionable but likely to play is receiver Paul Richardson, who showed up on Tuesday's injury report with a groin injury.
"He just felt some tightness, so we just took care of him during the week," Carroll said. "He should be all right, should be OK."
Defensive end Marcus Smith will not play this week due to a concussion sustained in Sunday's game, but Carroll said, "He should be fine next week."
Also out is running back Eddie Lacy, who left Sunday's game with a groin injury. The Seahawks will be getting help at that position, with C.J. Prosise expected back after missing the four of the previous five games with an ankle injury.
That time off might limit Prosise's playing time Thursday, but not the ways in which Seattle might use the versatile back, Carroll said: "There's no limitations on it other than how much we want to play him. We just want to get him back going and get him to help us out some, get him back in full flow."
