KEVIN KOLB had his right foot in a walking boot yesterday to protect a turf-toe injury and the Arizona quarterback said he had “no idea” whether he would be able to play in 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 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.”The Cardinals visit the Eagles on Nov. 13. Noteworthy * Hakeem Nicks, the New York Giants’ top receiver, tweaked a hamstring on the next-to-last series of the 20-17 win over Miami and his status for Sunday’s game at New England is uncertain.The most serious injury was a broken right arm suffered by defensive back Justin Tryon, who played the final 2 1/2 quarters with the injury, not telling team trainers about it.

Also, Texans wide receiver Andre Johnson could be cleared to play after missing four games with a right hamstring injury.* St. Louis quarterback Sam Bradford is no longer wearing a protective boot on his left ankle and began to exercise. Bradford, recovering from a high ankle sprain, has missed the past two games.* Indianapolis will keep quarterback Peyton Manning on the active roster so he can practice later this season and the team can determine whether he’s recovered from September’s neck surgery. In last night’s game * At Kansas City, Ryan Succop’s 30-yard field goal in overtime lifted the Chiefs (4-3) over San Diego (4-3), 23-20, in an AFC West clash.Former West Catholic star Curtis Brinkley’s 2-yard run and two-point conversion reception from Philip Rivers enabled the Chargers to forge a 20-20 tie midway through the fourth quarter.The Chargers had a chance to take a lead with less than a minute left in regulation but Rivers fumbled the snap exchange and the Chiefs recovered.
