Aaron Gray remains at the Detroit Pistons' practice facility helping put big men through drills while being sidelined after a cardiac episode over the summer.

"I had my first kind of 'shock' here," Gray said, referring to the Pistons' practice facility, "then it was kind of a rollercoaster over the next two days."

Gray does extensive cardio exercises and undergoes regular testing.

"We're just taking it one step at a time right now -- still gathering information, same old answers -- and preparing for the next step," Gray said. "What step we're on, or what step we'll get to, I don't know. Eventually, there will have to be a decision on whether I can play basketball again or not."

Gray was waived and the Pistons traded for Joel Anthony to replace his roster spot since he would not likely be cleared.

Gray stayed for his rehabilitation and remains active in the game by drilling big men for a team that released him.

"They brought me here for a service," Gray said. "Even though I've been waived, the type of guy I am, I'm still getting paid for two years. I just wouldn't feel right not contributing as much as I possibly could.

"The organization's been great. It's been great being around the bigs, giving them as much knowledge as I can, helping out as much as possible, and just being able to use the facilities during my rehab."
