For a moment, Keith Langford felt as if his left arm had been extracted from his body.

“You’ve got somebody 260 pounds falling on your elbow … it’s tough. I had to look and see if my arm was still there. It didn’t feel like it,” said Langford, KU’s senior guard who hyperextended his left arm when power forward Wayne Simien fell on him two minutes into Saturday’s 89-60 rout of Colorado at Allen Fieldhouse.

“Wayne apologized to me on the bench. It was all in good hustle, so everything’s good. It’s pretty sore, but I’m fine.”

The two players were chasing the basketball playing defense when Simien banged into Langford.

“I didn’t even know I hurt him,” Simien said of Langford, who, after getting checked in the locker room, returned and finished with 14 points, four rebounds and four assists in 29 minutes. “Keith told me when we were sitting on the bench. Obviously, I apologized. He said it was a loose ball and hustle he wants to see, so it’s what we’ve got to do.”

KU coach Bill Self knew Langford would return.

“I asked him if it was his funny bone. He said, ‘No, I hyperextended it,”’ Self said. “They went and checked it. I knew he’d be back. You can’t keep him out of a game now.”

Freshman forward C.J. Giles, who has a bruised right foot, played for the first time in seven games. He had three rebounds in six minutes.

“We know one thing: He hadn’t forgotten how to foul,” Self quipped of Giles, who had four fouls. “I think he can be real important to us. We need him.”

Giles said he felt pain during his stint.

“It will hurt until I’m 100 percent. I expect that. I’ll play through it,” said Giles, who said he did not have a stress fracture, but signs of a developing stress fracture which has necessitated rest. “The first couple of minutes I was out of breath. I have to get used to playing again.”

He said he was back for good.

“I have only a couple of more games to play with these incredible seniors. I’ll try to make the best of it I can,” he said.

Of his fouls, he said: “I hate when people score on me, so I have to do what I have to do to prevent that.”

Alex Galindo missed his fourth straight game because of a groin pull. And Moulaye Niang missed the game. He was kneed in the groin Friday at practice.

“Alex told me before the game he could play, but it was hurting,” Self said. “Moulaye got a knee in the groin, and it was very tender. He told me if I didn’t have to, to try to not play him. It’s the reason they didn’t play.”
