If fullback Jared Tew is unable to play Saturday – and as of Tuesday, his availability had not yet been determined – Air Force feels good about Tew’s replacement, Nathan Walker.

Walker, who went to Colorado Springs Christian High School, is one of the few local products on the Air Force roster. Coach Troy Calhoun indicated Tew will either play without a splint on his injured hand, or not play at all.

The status of tailback Asher Clark, who has an ankle injury, is also up in the air. He didn’t practice Tuesday, while Tew participated on a limited basis. With the backfield in flux, players like Walker and backup tailback Darius Jones could be asked to fill bigger roles, and perhaps start.

“That’s a possibility but I’ll prepare the same way every week, just practice hard and get ready to go,” Walker said. “Nothing different, really.”


National anthem request


Some Oklahoma fans sing “home of the Sooners” instead of “home of the brave” at the end of the national anthem. Out of respect for the Air Force, Sooners coach Bob Stoops asked that the fans sing it correctly Saturday.

“I am totally in agreement with our administration and most everybody that hopefully the people that will be singing ‘home of the brave’ can surely be louder and stronger than anybody that’s saying ‘the Sooners,’” Stoops said at his weekly press conference, which is archived on Oklahoma’s official site. “I have great respect for these young men and all the academies for their service, their commitment, their sacrifice.”
