Advocate staff photo by MATTHEW HINTON--New Orleans Saints tackle Terron Armstead (72) reacts to the dwindling seconds of the game against the Cincinnati Bengals as the Saints lost 27-10 in a NFL football game in the Superdome in New Orleans, La. Sunday, Nov. 16, 2014.

The New Orleans Saints’ best offensive lineman may not be available for Sunday’s game against the Philadelphia Eagles.

Left tackle Terron Armstead, who injured his left knee in the second quarter against Dallas, did not practice for the second day in a row, according to the official injury report the team submits to the NFL.

Armstead underwent an X-ray on his left knee at halftime against the Cowboys and returned, playing the entire second half.

If he misses time against Philadelphia, rookie Andrus Peat would take Armstead’s place on the left side.

Armstead’s partner on the left side, Tim Lelito, did not participate in practice due to a back injury, but Lelito was present during the portion open to the media. Punter Thomas Morstead, who is battling a strained quadricep, also did not practice.
