The Cowboys continue to churn the bottom of their 53-player roster. They worked out defensive tackle Drake Nevis last week and liked him enough to sign him Tuesday.
Nevis replaces Jerome Long on the roster. The Cowboys released Long, who appeared in the first three games but had no stats. Long played 27 plays Sunday against the Rams.
Nevis was a third-round choice of the Colts in 2011 and played in 14 games with them in two seasons, making 35 tackles and a sack. The Colts released the LSU product Aug. 31, and the Chargers claimed him off waivers. The Chargers released him Sept 17 after he was inactive the first two games.
The Cowboys are without starting defensive tackle Jay Ratliff for at least three more games. Ratliff is on the physically unable to perform list while recovering from a groin injury.
