Gundy said after the game that safeties Lavocheya Cooper and Isaac Maselera are no longer with the team.
Cooper, a junior from Arp, Texas, left the squad for undisclosed personal reasons. Gundy said Maselera's departure was for a violation of team rules.
Maselera, a sophomore from Glenpool, pleaded guilty to possession of drug paraphernalia on Monday, and received a six-month deferred sentence, community service and a fine.
MOORE, AND MORE
Charlie Moore was one of the busiest Cowboys on the field Saturday.
The junior receiver had eight receptions for 129 yards, both career highs. He had a 74-yard touchdown, his second straight game with a TD of 70-plus yards.
Moore was the fourth OSU receiver to have a 100-yard game this season, which is a single-season school record. Tracy Moore, Blake Jackson and Josh Stewart are the other three.
Charlie Moore also resumed the duties of punt returner. Iowa State punted nine times, and Moore had four returns for 28 yards.
ORANGE HELMETS DEBUT
Saturday brought the long-awaited arrival of Oklahoma State's orange helmets, which accompanied an all-orange uniform combination.
The helmets, which had white facemasks and a logo of Pistol Pete's head on each side, were generally well-accepted.
“The helmets were nice,” running back Joseph Randle said. “I liked the uniform today. I was hyped when I saw ‘em when I first walked in. We've been waiting a long time for those orange helmets.”
While most people seemed to like the new helmets, not everyone enjoyed the Clemson-like combination with orange jerseys and pants.
“Not a fan of the ALL orange OSU uni's. Helmets are pretty sweet but the combo is just too much!” former Cowboy quarterback Brandon Weeden posted on Twitter Saturday.
Weeden coordinated the Cowboys' uniform combinations last season.
According to OSU media relations, the last time OSU wore orange helmets was believed to be in 1979, and Saturday was believed to be the first time in school history that Pistol Pete was featured on the helmet.
Quarterback J.W. Walsh recorded his third 300-yard passing game — the most ever by an OSU freshman — and the 12th 400-yard passing game in OSU history. Walsh's 415 yards is the second-most by a freshman in OSU history, behind Lunt's 436-yard game at Arizona in September... Redshirt freshman receiver Torrance Carr saw his first career action after recovering from a preseason injury, but the 6-foot-2, 215-pounder did not catch a pass... When Iowa State scored on its opening drive Saturday, it marked the first game this season in which OSU did not score first... Saturday's attendance was 57,019.
