Allen Iverson is contemplating retirement if he doesn't return to the Grizzlies, sources told the Memphis Commercial Appeal.

Iverson left the team on Saturday after receiving permission from team owner Michael Heisley to deal with personal issues.

The source claims that the stress that comes along with the family issue, along with his frustration over his role in Memphis, may lead him to call it quits.

"I just think if he was going to retire, he'd tell me first," Heisley said. "I expect him to come back. If he does retire, I'll be tremendously disappointed. I feel bad because I don't think that's the way he should go out."
