TEMPE, Ariz. (AP) -- Kevin Kolb failed to practice again on Thursday, seemingly decreasing the likelihood the Arizona quarterback will be able to start when the Cardinals play at Philadelphia on Sunday.
He insisted, though, that there has been "dramatic improvement" in his right turf toe injury.
While John Skelton could be headed for his second straight start, coach Ken Whisenhunt raised the possibility that there could be a game-time decision to dress Kolb as the backup quarterback, even if he is unable to practice for the second week in a row.
Kolb dearly wants to play against his former team. He started seven games for the Eagles over a four-year span.
