Sports: David Griffin is out as GM of the Cleveland Cavaliers

David Griffin's uncertain future was becoming a problem in negotiations with other teams.

Owner Dan Gilbert released a statement saying that the two sides "mutually decided to not extend David's current contract."

Griffin's contract was set to expire at the end of June and according to several reports, the uncertainty of his future was causing problems with trade talks.

"Cavs front office had difficulty in trade talks this week, constantly needing to address Griffin's future with rival executives," Adrian Wojnarowski of The Vertical wrote on Twitter. "Tough spot."

As recently as April, LeBron James publicly declared his support for Griffin.

"It makes no sense why he shouldn't get an extension," James told ESPN. "He's pulled every move — he's tried to make every move happen — to better this team to be able to compete for a championship. So we wouldn't be in this position, obviously, without him and without the guys that are here — from the coaching staff to the players to Griff. He's been a big piece of it."

Wojnarowski added that "multiple teams" will be pursuing Griffin in the next round of GM openings "for significant money."

Gilbert did not announce a replacement for Griffin.
