Richard Hamilton, Rasheed Wallace and Allen Iverson participated in a full-team practice with the Pistons on Friday, which hasn't happened in over a month.
"They were all out there and they all looked good," coach Michael Curry said. "I am saying that everybody is going to play (Saturday in Washington) because I want to be positive. I told Abs (athletic trainer Mike Abdenour) to make sure he brings everybody's uniform."
Hamilton is the only player of the three that is certain to face the Wizards on Saturday night.
"Realistically, Allen probably won't play," Curry said. "The one I am most confident about is Rip. We will have to see how Allen and Sheed respond. Allen hasn't done anything for 15 games, so that's tough. Sheed and Rip both moved around real good. So hopefully with treatment and some rest they will be ready to play, at least in a limited role."
