The Nuggets are fighting to hold together a locker room that has grown frustrated with Carmelo Anthony's selfish play, reports Adrian Wojnarowski of Yahoo! Sports.

Several sources have indicated that Denver's players and coaching staff are frustrated with Anthony chasing shots and points over winning games, his refusal to listen to coach George Karl and how he has distanced himself from the team as the season has progressed.

For these reasons, few believe the Nuggets can still sign him to a three-year, $65 million extension.

"With the way he's distanced himself from the team, the organization, they're kidding themselves if they think he's signing a new deal," one league official told Yahoo! Sports. "He hasn't checked out on the season because he never checked in."

The Nuggets are working to sign Karl to an extension and sources claim he's more comfortable coaching the team without Anthony.
