Miami Heat rookie Shabazz Napier disavowed any knowledge that his Twitter account unfollowed LeBron James and deleted a series of tweets following James' decision to join the Cleveland Cavaliers.

"The whole thing about that is I don't know how to work Twitter yet and I'm not on my Twitter, so I don't know where that came from," Napier said following the Heat's 85-83 loss to the Washington Wizards at Las Vegas Summer League.

Napier joined Twitter on June 25, a day before he was drafted by the Heat. He followed James shortly thereafter. But days after James decided to return to Cleveland, the point guard's account, @ShabazzNapier, no longer follows James' account, @KingJames, and any tweets sent toward James have been removed.
