DE Walker doubtful

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.

Walker 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.
