Saints left tackle Terron Armstead is confident that he will be able to play this week against the Tampa Bay Buccaneers after suffering a concussion during Sunday's loss to the Dallas Cowboys.

"Any symptoms or anything went away pretty fast, so I had a feeling I was going to be good to go for the week," Armstead said.

Armstead, who was a limited participant in practice, was knocked out of action in the first quarter of Sunday's game and was replaced at left tackle by Bryce Harris.

Armstead said he did not know what initially caused the injury.

"I knew I took a blow, I didn't know from what," Armstead said. "It took me a kind of second to regroup."

Saints center Jonathan Goodwin (neck), running back Mark Ingram (hand), fullback Erik Lorig (ankle), and cornerback Corey White (foot) did not practice Wednesday. Goodwin's neck injury and White's foot injury are new additions to the injury report.

Safety Marcus Ball (hamstring), cornerback Patrick Robinson (thigh), and linebacker David Hawthorne (ankle) were limited.

Linebacker Curtis Lofton (shoulder) and tight end Benjamin Watson (groin) were full participants.
