Cowboys making cornerback changes

OXNARD, Calif. -- With Mike Jenkins out until maybe the third preseason game as he recovers from shoulder surgery, there are some changes coming in the secondary.

Defensive coordinator Rob Ryan said Akwasi Owusu-Ansah is moving from safety to cornerback. Teddy Williams, CJ Wilson and Mario Butler got second-team reps with Orlando Scandrick during Monday's walkthrough practice.

It's uncertain how many corners the Cowboys will take into the regular season.

It's expected Brandon Carr, Morris Claiborne, Scandrick and -- if he's healthy -- Jenkins will make the 53-man roster. How many they will keep will depend on how many defensive linemen make it and who can play well on special teams.

"Everybody is going to get an opportunity and we’ll see how it all works out," defensive coordinator Rob Ryan said. "That’s what preseason is for. We’re going to keep the best players, but we’re going to play everybody and make sure we keep the right guys -- the guys that will help us win. That’s what we’ll do."
