According to Alex Kennedy of hoopsworld.com, the Celtics were one of four teams present at free agent forward Adam Morrison‘s workout Tuesday in Las Vegas. The Bulls, Clippers and Cavaliers were also present for the workout.

Morrison, the third overall pick of the 2006 NBA draft, has been a major disappointment in his three professional seasons. He played with the Lakers last season, averaging 2.4 points and 1.0 rebounds in 31 games.
