The door is still cracked — backup QB John Skelton said "As far as I heard, Kevin is still a possibility" — but if Skelton doesn’t start Sunday, it’s an upset.
Kolb's injury, which is on his right foot, is affecting his ability to push off on his throws.
This would certainly be news to Kolb, who spoke to reporters about Wednesday's practice and said he did not have to wear a boot. SB Nation Arizona has been on top of this story from the beginning, responding to Shefter's tweet with a report that Kolb was not wearing a boot on Wednesday. Even with the boot issue in dispute, both parties seem to agree that Kolb's status is still up in the air for Sunday's game against the Rams.
A lack of depth behind Kolb is what makes his status so important for Sunday, as it's not as if he has set the world on fire since being traded to the Cardinals. On the season, Kolb has completed 56.8% of his passes, with 8 TDs and 8 INTs for a middling QB Rating of 77.8.
