Kevin Cosgrove has few complaints about the way his defense has played of late.

He did, however, register at least one concern about last week’s 22-20 loss to Texas.

“We missed some tackles,” the Husker defensive coordinator said. “I don’t care who you play, you can’t miss tackles. But as far as assignments and the blitz game and our base coverages and fronts, we played very well.

“We just needed to make a few more plays in critical situations.”

Nebraska’s defense anticipates a stern test Saturday at Oklahoma State, which ranks second in the Big 12 in total offense at 421.7 yards per game. The Huskers lead with an average of 434.9.

The Cowboys feature a balanced attack that is led by 6-foot-3, 225-pound quarterback Bobby Reid, who ranks third nationally in passing efficiency and also poses a threat on the ground.

“He has great speed — he’s a strong runner,” Cosgrove said. “He can create some problems.”

INJURY UPDATES: Husker starting middle linebacker Corey McKeon is limping slightly this week, still not fully recovered from the Oct. 14 game at Kansas State.

In addition to his ankle injury, McKeon said he also suffered a stretched and bruised MCL in his left knee against the Wildcats. He started and made two tackles in Nebraska’s loss to Texas.

“It’s annoying, but it really doesn’t stop you from playing when you loosen it up,” McKeon said of his knee.

As for his ankle, he suffered high, medium and low sprains, he said. The tendons are stretched in the area.

“I moved pretty well against Texas,” he said. “There is just that little restriction because you have all the (protective gear) on your leg. I still did my job and graded out high.”

Also, starting cornerback Andre Jones will play Saturday with a splint on his hand to protect a “slight fracture” that occurred in the Texas game, coach Bill Callahan said. It was unclear whether Jones fractured his hand or a finger.

MANN STATUS: After seeing significant playing time in a reserve role at Kansas State, Nebraska senior center Kurt Mann didn’t play at all against Texas. The Huskers chose to stick with junior Brett Byford, who replaced Mann as starter in the second game after Mann came down with mononucleosis. “We kind of gauged it off how Byford was playing,” Callahan said. “I thought Brett played a very good game.” The situation remains fluid, Callahan said.

ZAC’S TRAVELS: Five years ago, Nebraska quarterback Zac Taylor gave then-Oklahoma State head coach Les Miles an oral commitment to accept a scholarship offer. A native of Norman, Okla., Taylor eventually reneged and attended Wake Forest. You know the rest of the story. Taylor said he decided against OSU because it was clear Josh Fields, a true freshman at the time, was the school’s QB of the future. Fields played host to Taylor on Taylor’s recruiting trip to Stillwater. “When you walked around campus, you could see how people treated Josh — he was the guy,” Taylor said this week. “That’s just tough to compete with.”

GOOD RESPONSE: Callahan said his team has responded well in practice to the Texas loss. He said his players on Wednesday showed good focus and energy.
