David Stern is not pleased with LeBron James after the Cavaliers star refused to speak to the media, and did not shake his opponents' hands, after his team was eliminated from the NBA playoffs Saturday night against the Magic, the NBA commissioner acknowledged on ESPN Radio.

Stern said he has reached out to James but is reserving judgment about the situation until he speaks with him.

An NBA spokesman said on Monday that James would not be fined for failing to address the media after the Game 6 loss. ESPN Radio host Colin Cowherd asked Stern why James has not been fined since the league has punished players in the past for violating its media guidelines.

"I'm in the process of making a phone call or two now to talk to LeBron," Stern said, "so I don't want to speak to that at this moment."

But when asked if he is not happy with James, Stern replied, "I think that's fair to say."
