Actually according to this article... he doesn't look too ridiculous at all:
Miles has not played in an NBA game in two years, so it is not known when, or if, he was suspended five games during that time.
Although the Blazers waived Miles in April after an independent doctor ruled Miles' injuries to his right knee were career ending, the 10-game suspension is still relevant to the team. The Blazers will pay Miles the remaining $27.25 million of his contract, but his salary does not count against the Blazers' salary cap. However, if Miles returns to the NBA and plays in 10 games in one season in either of the next two seasons, his salary goes back onto the Blazers' books.
The suspension figures to make Miles even more damaged goods for a team interested in signing him. It is unclear whether Miles is trying to make a comeback, although it was rumored that he has been working out in Phoenix. His agent, Jeff Wechsler, did not return a phone message on Wednesday. No player has ever come back to the NBA after being deemed to have a career-ending injury.
