STILLWATER, Okla. (AP) — It didn’t make a difference who was playing quarterback in UL’s game against Oklahoma State on Saturday.

No matter who was running the show for the Cowboys, the points kept piling up. And regardless of who took the snaps for the Ragin’ Cajuns, the offense went nowhere.

Backup J.W. Walsh threw for 347 yards and four touchdowns in relief of injured starter Wes Lunt, leading Oklahoma State to a 65-24 blowout asUL’s Blaine Gautier and Terrance Broadway both struggled.

"Right now, we are not getting great quarterback play," coach Mark Hudspeth said. "We’re not getting bad quarterback play, but we are just not getting quarterback play that will allow us to score points."

Hudspeth pulled Gautier with his Ragin’ Cajuns already trailing 31-0 early in the second quarter. Broadway, who led the team to a win at Sun Belt rival Troy a week earlier when Gautier injured his ribs, didn’t fare any better.

"We couldn’t slow them down and we just weren’t getting things started on offense," said Gautier, who ended up with 236 yards passing, running for one score and throwing for another.

The Ragin’ Cajuns (2-1) managed only one first down by the time Oklahoma State took a 24-0 lead early in the second quarter, and the deficit ballooned to 44-0 by halftime. By that point, the Cowboys had a 450-104 advantage in total yards.

"You don’t ever want that to happen," Hudspeth said. "They are a better football team than we are. Are they that much better? I don’t think so."

Oklahoma State went on to set a school record with 742 yards of total offense, despite losing Lunt to a left knee injury on the sixth play of the game.

Lunt stayed face down on the field for a few moments after getting hit by cornerback Melvin White as he scrambled backward and threw an incomplete pass. Trainers helped him to the sidelines and he went to the locker room on crutches, with his injured left knee wrapped, late in the first quarter.

The Cowboys (2-1) didn’t miss a beat without him, scoring on all eight of their first-half possessions.

"The way the offense clicked today was just amazing," said Walsh, who also ran for 73 yards and a score. "Everyone, they were in the right spots, they were doing the right things, and it’s just good to know that you’ve got the offense moving like it was."

Coach Mike Gundy suggested that Lunt’s injury isn’t as bad as it looked, but he refused to provide specifics. Oklahoma State’s policy is to release injury information the day before a game, and Gundy said he was going to stick with that leading up to the Sept. 29 game against No. 14 Texas.

The Cowboys, who are off next week, also had reserve cornerback Devin Hedgepeth carted off with a left leg injury.

"It’s always unfortunate when you have a player that could have some sort of a severe injury — Wes or even Devin Hedgepeth," Gundy said. "That’s one of the most difficult parts of being a football coach, is to see a player that’s worked hard get injured. It just puts a knot in your stomach."

Walsh said his immediate reaction was to feel badly for Lunt, but then he knew he had work to do.

"He had a good look in his eye. There wasn’t any fear, in my opinion," Gundy said. "He went out and just played."

Walsh’s first pass attempt was batted down two plays after Lunt got hurt, and Oklahoma State settled for a 51-yard field goal by Quinn Sharp. After that, Walsh led the Cowboys on five straight drives for touchdowns.

Walsh threw a 52-yard touchdown pass that fullback Kye Staley caught behind the line of scrimmage before zooming up the sideline behind blocks from a caravan of receivers, and Blake Jackson jumped to catch a 20-yard TD pass one play after he’d made a 58-yard reception.

Josh Stewart added scoring catches of 33 and 17 yards and finished with 104 yards on nine catches. Jackson had five receptions for 112 yards.

Joseph Randle ran for 105 yards and two scores for Oklahoma State, which rebounded from a 59-38 loss at Arizona.

UL got its first touchdown when Gautier found Darryl Surgent wide open for a 73-yard pass after Hedgepeth crumpled to the ground with his injury. Hedgepeth missed much of last season with a ruptured Achilles tendon and was playing as Oklahoma State started to rotate more bench players in.

Marcus Jackson added a 1-yard touchdown run and Brett Baer connected on a 41-yard field goal for the Ragin’ Cajuns, who were trying to start 3-0 for the first time since 1988.

Baer had made 18 straight made field goals before missing a 44-yarder in the first half.
