CLEMSON -- Dabo Swinney is not ruling out left tackle Chris Hairston for Saturday's home game against TCU.

Swinney said Hairston was able to walk without crutches Sunday and has only minor swelling after spraining the MCL in his left knee during Saturday's win against Boston College.

Hairston's health is critical as the Tigers already have issues at right tackle, and TCU possesses one of the nation's elite edge rushers in Jerry Hughes.

Recovery time from a knee sprain usually involves several weeks of rest, but Swinney wouldn't rule out Hairston,

whose knee was rolled upon Saturday.

"He looked fairly good this morning," Swinney said of Hairston. "We'll have to wait and see how it goes the next couple days. Right now I just don't know. He didn't have crutches. He didn't have a knee brace. He was walking, carrying his own weight.

"That's pretty good when you have a MCL sprain."

If Hairston can't go, the question was raised of how the Tigers will slow Hughes, especially after what Georgia Tech's Derrick Morgan wrought.

"We'll have to have a plan no doubt," Swinney said. "He can run full speed under a table, he is a very good player. We'll have to have a Plan A, B and C for him. Give ourselves a chance to hopefully minimize him a bit."

The other health question mark hovers above the toe of C.J. Spiller, who has missed parts of two games due to what has been labeled a "jammed" toe.

Spiller said it is not the dreaded turf toe injury, which often requires surgery.

"He was good (Sunday) morning," Swinney said. "He felt better this morning. He'll be ready to go. It's amazing what he is doing."

Swinney said he would not consider resting Hairston or Spiller because Saturday's game is a nonconference game against the No. 14 Horned Frogs.

"I don't think our fans think that way," Swinney said. "We certainly don't think that way.

"We try to win every game."

Swinney didn't have much new to add Sunday, noting that the red zone offense must improve and there have been too many "misfires" along the offensive front.

He was pleased that the offense possessed the ball for 11 1/2 minutes in the fourth quarter Saturday.

"This is a very common issue -- making critical errors," Swinney said of the offensive execution. "We gotta coach better. It's not what the opponent is doing, it is what we are doing."

Depth charge

Wide receiver Marquan Jones officially displaced Terrance Ashe on the updated depth chart Sunday. The starters at receiver for the TCU game include Jones, Jacoby Ford and Brandon Clear. … Swinney said the Tigers allowed only three big plays Saturday, after allowing 10 in Atlanta. Clemson limited Boston College to 54 yards on 49 plays.
