Walsh played through injury, but is now sidelined

During his regular Sunday evening teleconference, Oklahoma State coach Mike Gundy announced quarterback J.W. Walsh has been ruled out for the rest of the season due to a knee injury he suffered against Iowa State on Saturday.

"He just has an injury that I don't think anybody wants to reveal, but he just has an injury with his knee," Gundy said. "It is not career-threatening or anything, but he is finished for the season."

Walsh passed for 415 yards and a touchdown while rushing for 52 yards and a score in Saturday's game, and when he suffered the injury isn't exactly clear.

The most likely time was when the redshirt freshman was taken down for Iowa State's only sack of the game. Walsh slowly rose after the hit, and favored his right leg with a noticeable limp. Though he didn't miss a play, Walsh continued to show that something was wrong from time to time.

When asked about the play after the game, Walsh said that he was fine and "just got up slow." He went on to say that he was "one-hundred percent."

Walking into and out of the press conference, Walsh didn't show any noticeable signs of injury or a limp. Gundy hinted that he was aware of the injury at the time it occurred, but obviously didn't think it was anything major as he let the quarterback finish the game.

"It just happened and he was able to play with the pain," Gundy said. "I can only say that it was a pretty amazing performance. I would hate to use that term for a guy or a player on my team that is only a freshman, but for him to finish the game the way he did and run the football and never say a word was a terrific performance."

Walsh has appeared in every game this season, though his playing time against Arizona was for only one snap. With six appearances, Walsh is ineligible for a medical redshirt designation.

Since taking over for injured starter Wes Lunt on September 15th, Walsh has passed for 1,318 yards, 8 touchdowns and 2 interceptions while adding another 225 yards and 3 scores on the ground in four games.

Lunt, who has practiced since the team's game against Texas three weeks ago, is expected to return to his starting role on Saturday against TCU. Lunt is listed as the QB1 on OSU's depth chart in its weekly release.

Before the injury, Lunt played one quarter against Savannah State in the season-opener and the full game against Arizona. He passed for 588 yards, 4 touchdowns and 3 interceptions during that span, including a Big 12 freshman record 436 yards against the Wildcats.

Junior Clint Chelf, who was the backup for Brandon Weeden last season, will likely move into the backup role for the rest of the season.
