METAIRIE, La. – There were no updates available Monday on New Orleans Saints left tackle Terron Armstead’s status for this week's game against the Tampa Bay Buccaneers after he left this past Sunday night’s game early with a concussion.

Coach Sean Payton said Armstead will go through the NFL’s mandatory concussion-evaluation protocol during the week, and “we’ll wait and see where Terron’s at.”

Payton did confirm that third-year pro Bryce Harris would remain Armstead’s replacement if needed, after he said Harris was one of the few bright spots during the Saints’ 38-17 loss at the Dallas Cowboys.

“I thought Bryce did a pretty good job of stepping in there. Looking at the tape, he played pretty well,” Payton said of the 6-foot-6, 300-pounder, who made his NFL starting debut at left tackle after starting one game at right tackle in both 2012 and 2013.

It was especially impressive that Harris held up in a situation where the Saints were forced to throw the ball on almost every snap as the game wore on.

If Armstead can’t play, however, the Saints will have to identify an even less-proven backup option for Harris. They have two backup guard/centers on the roster in Tim Lelito and Senio Kelemete, but neither was cross-trained at tackle this summer. Rookie Tavon Rooks could be activated from the practice squad. Or the Saints could look elsewhere for help.
