Celtics president of basketball operations Danny Ainge said the team will know more about the status of concussed guard Mickael Pietrus next week, but reaffirmed that the team expects him back this season.

Making his weekly appearance on Boston sports radio WEEI (93.7 FM), Ainge said Pietrus is still exhibiting concussion symptoms after his scary fall last Friday in Philadelphia. He stressed that Pietrus is getting better each day and the team is in no rush to get him back on the floor.

From WEEI.com:

"He still has concussion symptoms and until he's asymptomatic, no headaches and no sensitivity to light, we won't even be able to test him," Ainge said. "The league has implemented new procedures once he becomes asymptotic and he's not there yet, although he is improving each day."

Asked if he thought there was a chance that Pietrus doesn't return this season, Ainge said, "We're not thinking that way at all. There's not a whole lot we can do. If we find that information out we'll have to react and go get someone out of the D-League or something. Right now, I don't see how that would happen. He is getting better each day.

"I anticipate within the week that he'll start getting tested and get back to practice," Ainge continued. "I don't know how long that process goes either. We're not in a rush to get him back as much as we want him to come back and be healthy. I think we'll know more in the next four or five days."

Pietrus escaped serious injury in Philadelphia, but under new NBA regulations this season, he must pass a series of concussion tests in order to be cleared to return to on-court activity.
