Deron Williams was out of shape before aggravating an ankle injury at the London Olympics, USA Basketball president Jerry Colangelo said.

Williams has struggled at times during his first season in Brooklyn, and the Nets have maintained his body is worn down because of nonstop playing over the last two summers.

“Deron Williams, for the Olympics, was not in the best shape,” Colangelo said. “He was a little overweight, and I told him that at the time.”

Williams has missed 23 games since joining the Nets.

Williams underwent platelet rich plasma injections in both ankles this week.

“I feel close to Deron, both from being from Illinois, and (from when) he was playing at Illinois . . . so I think I know him pretty well,” Colangelo said. “He’s a heck of a player, great guy, made a real contribution to USA Basketball and if he decides that he can’t participate because of his own health conditions, I’ve got a list a mile long of people who want to play."
