A report Friday by The Oregonian, a Portland, Ore., newspaper, said the team learned that the 7-footer participated in a pickup game Wednesday night in Tualatin, Ore.
He won't play in an NBA game this season but on March 14 practiced for the first time since his knee surgery in September.
At that time, he also worked one-on-one with assistant coach Maurice Lucas and even got in a couple of dunks, but his lone clearance was for light drills with the Trail Blazers and a probable return before the team's training camp for next season.
"We heard about that, and I talked to him," Portland Coach Nate McMillan told The
Oregonian. "I let him know he can't do that. We have plenty of workout equipment and gym space at our facility."
