Backup NT Josh Brent sprains knee

ARLINGTON, Texas -- Backup nose tackle Josh Brent suffered a sprained left knee on the point-after attempt following Laurent Robinson’s 18-yard touchdown catch in the fourth quarter.

Brent remained on the field for a few minutes but was able to walk off under his own power.

If he cannot return, then the Cowboys would use Sean Lissemore as a backup to Jay Ratliff.
