Cornerback Brandon Browner (hamstring) will be a game-time decision, Carroll said. If he can't go, Walter Thurmond and Byron Maxwell will see action. He would not elaborate how he intended to divvy up the duties of outside cornerback and slot cornerback.
Leo Cliff Avril, too, will be a game-time decision. He said earlier in the week that O'Brien Schofield would likely get the start at the pass-rush end. Carroll said that Chris Clemons, the expected starter at Leo, will be "full go" next week.
Defensive tackles Brandon Mebane and Tony McDaniel are expected to be a full speed, however. Carroll said that LG James Carpenter had a good week in practice and should be available to spell starter Paul McQuistan.
Asked about a recent tweet by injured receiver Percy Harvin (hip) that he'd be back by mid-season, Carroll said that he believes Harvin will surprise the doctors and that he's heard nothing but positive reports from doctors.
Of the Carolina game Sunday, Carroll said: "Everything's led to this," he said. "It's a very difficult matchup with these guys."
