Terron Armstead appears to be getting healthy just in time.

Armstead, who has missed the last three games with a knee injury, was limited in practice on Wednesday, just in time to take over left tackle after Andrus Peat suffered a groin injury against Carolina on Sunday.

Peat did not practice on Wednesday.

"We had him out there for quite a few reps, and it looked like he was moving around pretty well, so we'll see how it goes," center Max Unger said.

New Orleans has been able to handle a rash of the injuries to the left side of the line well this season. Armstead, Peat, Senio Kelemete, Tim Lelito and Tony Hills have all played significant snaps at one point or the other, but the Saints' offense keeps rolling.

"It speaks well to our depth," Unger said. "We've had guys that have gotten a lot of snaps this last couple of years at positions they haven't normally played."

New Orleans could also get back the services of defensive end Paul Kruger, who is trying to return from a back injury suffered against San Diego.

Kruger did not practice Wednesday, but he's optimistic that he might be able to return against the Chiefs. 

"It's just a tough deal," Kruger said. "It's kind of one of those things when it flares up, you just never know when it's going to subside, so I'm just trying to get treatment and get healthy and get back on the field."

Kruger, who felt like he was starting to hit his stride when he suffered the injury, said the key is making sure he's healthy enough that playing won't aggravate the injury.

"It's one of those things where the nerves are getting really irritated, and it restricts a lot of your movement," Kruger said. "Just trying to get that loosened up and get to the point where you have strength in your core."

Cornerbacks Delvin Breaux (fibula) and Sterling Moore (abdomen), along with linebacker Dannell Ellerbe (quad) did not practice Wednesday due to injury.
