Texans keeping eye on Carr's ankle, Walker's toe

HOUSTON -- The Texans already are planning to be without David Carr on Sunday when they are host to the first-place Panthers. Pro Bowl defensive end Gary Walker, also considered doubtful, could be gone even longer.

Walkers said Wednesday the "worst-case scenario" for the inflamed big toe on his right foot is that he would miss the remainder of the season. However, he's hopeful rest will heal the injury, but coach Dom Capers later said he didn't expect it to land Walker on the injured reserve.

Capers added that team doctors and trainers don't believe the injury, which Walker suffered Sept. 28 against Jacksonville and aggravated two games later against the Jets, would cause him to miss the rest of the season.

Walker was more grim when discussing it earlier in the locker room.

"I'm not giving up on it. I'm trying to be positive about the whole situation," said Walker, who missed the first part of the season with a sprained left shoulder. "There's something there that has to be dealt with -- for how long we don't know for sure. Nobody knows."

The news on Carr, who sprained his right ankle in Sunday's loss to Indianapolis, was better. Last year's No. 1 overall draft choice has missed just one game since fifth grade -- he sat out after getting speared in the back in high school -- and was visibly antsy hovering around practice Wednesday with nothing to do.

"Whenever I can get back to putting pressure on it dropping back, that's going to be the important thing," Carr said.

If Carr is out, Tony Banks' backup will be rookie Dave Ragone. If both were hurt, the Texans either would turn to wide receiver Jabar Gaffney or bring in Carr exclusively to hand off.
