Rajon Rondo will not sign a new contract with the Celtics, according to agent Bill Duffy.

The two sides met to discuss a possible deal recently. Duffy feels as though Rondo should be among the top-five highest paid point guards, but the Celtics don't feel the same way.

"We're not going to do an extension right now," Duffy told Yahoo! Sports. "The conversation has been cordial. We've been talking the last couple of weeks. There is a difference between the perception of him in their eyes and our eyes. With that being said, the focus is on Rajon to have a fantastic season and concentrate on winning a championship."

Assuming the two sides don't reach an agreement by Friday, Rondo will become a restricted free agent at the end of the season.
