Terron Armstead, made the Saints’ starting left tackle late this past season, underwent a small surgical procedure in one of his hands Tuesday morning, he announced to his Twitter followers.

“Minor hand surgery in the morning!!” he tweeted late Monday, prompting messages of support from Saints fans. “Praying for success and a speedy recovery.”

There’s nothing to indicate Armstead wouldn’t enjoy the kind of recovery for which he was praying.

Armstead, a third-round draft pick from Arkansas-Pine Bluff in 2013, began protecting quarterback Drew Brees’ blind side after Week 15, when left tackle Charles Brown failed to contain St. Louis defensive end Robert Quinn in a 27-16 defeat for New Orleans.

He struggled in the first half of his debut, a 17-13 loss at Carolina in Week 16; but he impressed the rest of the way, including a 42-17 win in the regular-season finale against Tampa Bay, a 26-24 victory at Philadelphia in a wild-card playoff and the season-ending 23-15 loss to Seattle in the divisional round.

Armstead attributed his quick improvement to “just getting comfortable.”

It was, he said, “getting experience, the game speed, game flow, … knowing what to expect.”

Coach Sean Payton added: “From the day he was inserted, … he showed a lot.”
