NEW ORLEANS –Cowboys starting left tackle Tyron Smith suffered an apparent ankle sprain on the final drive of Sunday's 12-10 loss to the Saints at the Superdome.
Smith accidentally got his leg rolled up while quarterback Dak Prescott took a sack inside the Cowboys' 5-yard line, with the offense trying to cobble together a winning scoring drive in the final 1:39 of regulation.
Smith left for the locker room in a cart. He traveled back to Dallas with the team in a protective boot, able to walk under his own power.
Immediately after the game, Cowboys owner/general manager Jerry Jones confirmed that Smith hurt his ankle. Smith will be re-evaluated Monday.
The Pro Bowl tackle and nine-year veteran has battled through back, knee and shoulder injuries in recent seasons.
Cameron Fleming replaced Smith for the remainder of the drive, which ended with a Prescott Hail Mary attempt that was intercepted. Fleming would be in line to start if Smith misses any more time. The Cowboys are back at AT&T Stadium this Sunday to face the Green Bay Packers.
