Cowboys starting quarterback Wes Lunt was forced out of Saturday's 44-30 loss to Kansas State due to concussion-like symptoms.
He was replaced by Clint Chelf.
On OSU's opening possession of the second half, Lunt was nailed by K-State defensive end Meshak Williams just after releasing a screen pass to Joseph Randle. Lunt laid on the turf for a moment, before getting up slowly.
He remained in the game, completing a 27-yard pass to Blake Webb before throwing an interception on the next play.
Once on the sideline, Lunt appeared groggy and was given constant attention by team doctor Val Gene Iven. Late in the third quarter, Lunt was escorted to the OSU locker room.
Cowboys coach Mike Gundy declined to address Lunt's condition, leaving the quarterback's status unknown.
Lunt's final stats: 11-of-20, 184 passing yards, one touchdown and three interceptions.
UP NEXT: WEST VIRGINIA
The Cowboys return home to face West Virginia, which lost to TCU 39-38 in double-overtime Saturday.
The Mountaineers are 5-3 overall and 2-3 in the Big 12.
This will be the first Big 12 meeting between the two teams in West Virginia's debut season in the conference. The Mountaineers are coached by former OSU offensive coordinator Dana Holgorsen.
COWBOYS GO DEEP, AGAIN
When Lunt hit Austin Hays for a 54-yard touchdown pass in the first quarter, it marked the Cowboys' fifth TD toss of 40 or more yards this season.
And OSU has three touchdown passes of 50 yards or longer in three of its past four games.
* J.W. Walsh to Charlie Moore for 74 yards against Iowa State.
* Walsh to Moore for 72 yards against Kansas.
* Lunt to Hays for 54 against Kansas State.
* Walsh to Kye Staley for 52 yards against Louisiana-Lafayette.
* Walsh to Josh Stewart for 44 yards against Texas.
Lunt set up the deep ball to Hays with play-action, selling a fake handoff to Jeremy Smith. Randle had carried the previous four plays for 14 yards.
For Hays, it was the true freshman's second touchdown of the season.
GUNDY ENDORSES WILDCATS, SORT OF
After the loss, Gundy was asked if No. 2 Kansas State was a worthy contender in the chase for the national championship.
He didn't offer a full-on endorsement, but didn't dismiss them at all, either.
“There's probably four or five teams now that in somebody's opinion has a chance to play for that,” Gundy said. “We would love for somebody from our league to have an opportunity to play for it.
“I don't watch the other teams enough. But they're a good football team. They don't make mistakes. They've got a very mature quarterback who makes plays. And could be arguably the best team in the country in special teams.”
K-STATE'S LOCKETT GETS LOOSE
Wildcats' receiver and return man Tyler Lockett, a product of Tulsa's Booker T. Washington High School, exposed the Cowboys kickoff coverage unit.
Lockett's highlight was a 100-yard return for a touchdown after a Quinn Sharp field goal had cut K-State's lead to 17-10.
It was Lockett's fourth career kickoff return for a touchdown, tying him with two Cowboys, one present and one past — Justin Gilbert and Perrish Cox — for fourth place in the Big 12 record book.
Lockett finished with 127 yards on three kickoff returns.
“We had a few returns that were very positive,” said K-State coach Bill Snyder. “He and (Tramaine) Thompson are both quality return men, but it takes 10 other guys. And the other 10 did a nice job.”
* OSU eclipsed the 500-yard mark for total offense for the sixth time in eight games this season.
* Desmond Roland's 80-yard kickoff return for a touchdown is the longest play by a Cowboy this season.
* Charlie Moore's 13-yard touchdown reception in the fourth quarter marked the fourth straight game he's scored a TD.
* Stewart caught eight passes, giving him 56 this season.
* K-State's 31 points through two quarters were the most scored against the Cowboys by halftime this season.
