"It's gotten a lot better since Monday," Brees said. "My hope is and ... I'm very confident that by game day it will be fine."
"There's no specific injury other than he has soreness," Payton said. "He took all the (practice snaps). There's not an injury to report. I was pleased with how he functioned. He functioned fine. It's something that as the week goes on, I think he'll have no problem with, and he did a real good job in all the team stuff today."
Brees said he wasn't sure whether or not he'd wear the brace during Sunday's home game against the winless Carolina Panthers.
"I'm kind of playing with it for stability and comfort," Brees said. "More than likely, yes. We'll see."
Brees' knee started bothering him last Sunday after he took a hit from Falcons defensive end John Abraham, who tackled the quarterback during a fourth-down pass to Jeremy Shockey to extend a game-tying drive.
"Fortunately the soreness for him is not as significant as you might expect with some ankles," Payton said. "It's not a high ankle sprain. It's not any of that, but there is swelling enough to where we held him out today."
Harper was in and out of Sunday's game, often having his leg stretched on the sideline.
Payton didn't expand on Harper's injury, and neither Harper nor Thomas were in the locker room when it was open to reporters Wednesday.
