TEMPE, Ariz. -- Arizona quarterback Kevin Kolb had his right foot in a walking boot on Monday to protect a turf toe injury and said he had "no idea" whether he would be able to play in next Sunday's home game against the St. Louis Rams.
Kolb was injured early in Sunday's 30-27 loss at Baltimore but stayed in the game.
"I did some things to help with the pain a little bit," he said, "then just tried to gut it out and try to come up with a victory."
If Kolb can't go, second-year pro John Skelton probably would get the start. Skelton started four games late last season. A turf toe occurs when the toe is jammed severely, stretching the ligaments.
Kolb said he has had the injury before but not "near this severe."
Kolb said his initial plans are to work to reduce the swelling and pain, "then as the week goes on give it more and more movement and see what my body allows me to do."
Kolb, who ran for a first down late in the game, said the injury didn't affect his mobility so much as it did the velocity of his passes, since he pushes off with his right foot.
"A lot of your power comes from that side of your foot," Kolb said, "on that leg. When I had to take off and run I didn't feel it or anything. It probably was just nagging a little bit but nothing to throw me off my game."
Consecutive games against two of the best defenses in the NFL, Pittsburgh and Baltimore, has left Arizona's offense a bit battered. Rookie Anthony Sherman, the team's only fullback, has turf toe on his left foot. Running back Beanie Wells is playing with a sore knee.
Kolb has been sacked 24 time in seven games. The pressure he faced Sunday was his most severe yet. Of course, since it was Baltimore, that shouldn't be surprising.
"They run a tough scheme and bring them from a lot of different places. You've got to step up in there and block them," coach Ken Whisenhunt said. "We have to get the ball out quicker in some situations. We had opportunities to make them pay yesterday a couple of times, but we weren't as efficient as we needed to be from a protection standpoint or from getting the ball out. That's always tough.
"When you add in the noise, knowing your guys are going to be late off the ball, giving them the advantage, it is really a tough situation. I don't think people appreciate how difficult that is. That's why they're a good defense and they're a tough team to play there."
It was Arizona's fourth loss by four points or fewer, and this one was especially hard to take. The Cardinals, big underdogs, took advantage of two turnovers to score 14 points and take an early 24-3 lead only to see the Ravens run off 24 straight to go on top 27-24. Still, Arizona tied it at 27-27 before giving up a late drive that resulted in a last-second 25-yard field goal by Billy Cundiff to give Baltimore the win.
There's not a lot for the fans to cheer about, and that has led to concern the game against the Rams won't be a sellout. The Cardinals have sold out every home game since University of Phoenix Stadium opened in 2006.
"We're working hard to try to make sure we're taking care of business, and we haven't done that," Whisenhunt said. "It's been a tough stretch for our fans, I understand that, and we're working hard to try to get that fixed. Hopefully, they'll continue to support us. We've had a number of exciting games there and they've been a big part of that. All I can tell you is that we're going to have more there, and we sure would appreciate the support."
After Sunday's game, Arizona plays three in a row on the road, where they have lost 11 straight dating to the 2010 season opener at St. Louis.
