McKnight, who is coming off a game in which he rushed for a career-high 143 yards, was wearing a boot on the sidelines and Coach Carroll didn't seem too optimistic about his chances of playing against the Cougars.
"It's going to be hard for him to make it unless he makes a big turnaround," Carroll said after Tuesday's practice at Howard Jones Field.
"He's not moving very well on it now. He can't get out of the boot yet."
McKnight is scheduled to meet with team doctors on Tuesday night to examine his injured toe.
With McKnight and Marc Tyler missing action due to injuries, and Stafon Johnson missing Monday's practice with an illness, Broderick Green has been thrust into action with the first-team offense in practice this week.
"He's doing good. He's really come alive in the last few weeks," Carroll said of Green. "We have always wanted him to run big and he's doing that."
The bruising redshirt freshman who has received only nine carries this season could get significant playing time this Saturday in Pullman, WA.
Harris Moves to Tight End
Defensive tackle DaJohn Harris has switched to the offensive side of the ball and caught some passes from Mark Sanchez as a tight end on Tuesday.
Harris, who tips the scales somewhere in the neighborhood of 300 pounds, was moved to the tight end because of depth issues at the position. Rhett Ellison is sidelined with a hairline fracture of his fibula and Blake Ayles has been hampered recently with a possible sports hernia.
"We are just so thin there at that spot that we needed to do something, so we called and talked to him about it today and he was all for it," said Carroll.
Harris, who joked that he hasn't participated in 7-on-7 since high school, impressed Pete Carroll in his first day on offense.
"He's got great hands," Carroll said. "He was a slot receiver in high school so we knew he could catch the football.
"In the next few weeks I would think he could help us."
Carroll said he hasn't determined whether the switch will be permanent or just a temporary fix.
Bradford Likely to Redshirt
USC tailback Allen Bradford said that he has a tear in his labrum and prefers to redshirt this season, so he can make a full recovery from the injury.
"I don't want to come back and make it worse," Bradford said.
The junior tailback will meet with a hip specialist on Thursday to determine the best course of action for his injured hip and said surgery is a real possibility.
