Bill Nagy suffers high ankle sprain

OXNARD, Calif. – Bill Nagy's bid to compete for the Cowboys' starting center spot will have to wait.

Nagy suffered a high left ankle sprain in Monday’s practice and will have an MRI Tuesday to determine the severity. It’s the same ankle Nagy broke last year as a rookie and forced him on injured reserve.

Coach Jason Garrett did not have a timetable for Nagy's return.

"He's not going to practice anytime real soon," Garrett said.

Nagy started four games in 2011 at left guard before getting hurt at New England but spent almost all of the offseason exclusively at center in which he was expected to compete with Phil Costa. The only other healthy center on the roster is undrafted rookie Harland Gunn. Mackenzy Bernadeau (hip) and Kevin Kowalski (ankle) are on the physically unable to perform list.

When he is healthy enough to practice, the Cowboys want Bernadeau to concentrate on guard after missing the offseason because of hip and knee surgeries.
