TEMPE - Kevin Kolb is probably lucky he's only in a walking boot and not a body cast. The Cardinals quarterback has been hit so many times this season, he should be in traction.
After suffering a bad case of turf toe early during Arizona's 30-27 loss Sunday in Baltimore, Kolb said he has "no idea" whether he will be able to play in Sunday's home game against the St. Louis Rams.
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 has been sacked 24 times already this season, the second most in the NFL behind Pittsburgh's Ben Roethlisberger (25).
So what does the Cardinals' offensive line have to say about all this?
"We've got to play perfect. We know that," starting left guard Daryn Colledge said. "That's what we expect out of ourselves."
Coach Ken Whisenhunt isn't ruling out making changes on the line, including left tackle Levi Brown.
"I think when you're 1-6, you've got to look at anything," Whisenhunt said.
It isn't all the line's fault. Kolb said he must improve getting rid of the ball and being faster with his reads.
The Ravens sacked him six times and hurried him all day. That he had to run for his life with a jammed big right toe didn't help any. Trying to throw the ball with a weakened plant foot also sapped his arm strength.
"A lot of your power comes from that side of your foot," he said, "on that leg. When I had to take off and run, I didn't feel it. It probably was just nagging a little bit, but nothing to throw me off my game."
Manning still on roster
INDIANAPOLIS - Bill Polian plans to keep Peyton Manning on the active roster all season - even if it means the quarterback will only be back to practice.
The Colts' vice chairman didn't rule out a late cameo appearance by Manning this season, but for the moment he's only hoping Manning will be able to throw at the team's complex to "feel like, 'Hey I'm back,'" Polian said.
• Top New York Giants receiver Hakeem Nicks, their only deep threat, tweaked a hamstring on the the next-to-last series of a win over Miami and his status for Sunday's game against New England is uncertain.
• Montario Hardesty tore a calf muscle in Sunday's loss at San Francisco, leaving Cleveland with just one healthy running back. Hardesty is out indefinitely.
• St. Louis Rams quarterback Sam Bradford is no longer wearing a protective boot on his sprained left ankle and exercised for the first time Monday.
• The Washington Redskins claimed running back Tashard Choice off waivers. Choice was waived-injured by Dallas on Saturday. He had suffered a shoulder injury the previous week against St. Louis.
• Pittsburgh safety Troy Polamalu's slapping of the ball into the end zone at the end of the Steelers' victory over New England was against an NFL rule.
• Tennessee says Chris Johnson will remain the starting running back, despite being held under 35 yards four times this year. Backup Javon Ringer will continue to see some carries.
• The New York Jets have signed free agent tight end Shawn Nelson, a former Buffalo Bills fourth-round draft pick.
