Chris Paul is not interested in signing an extension with the Celtics, according to a source close to the situation.

Boston has been mentioned as a team that is angling to execute a trade for Paul.

Chris Broussard reported on Monday that Paul's preference is to end up with the Knicks and that he would also consider the Clippers.

While the Clippers would be an alternative choice for Chris Paul if he is unable to end up with the Knicks, the team's preference is to pursue Dwight Howard by all means necessary, say sources.

The Clippers will do everything they can to acquire Howard short of trading Blake Griffin.

Howard and Paul are members of the 2012 free agency class.

RealGM's Jarrod Rudolph reported earlier on Monday that Howard won't be interested in playing for the Clippers. Rudolph also reports that the Celtics will pursue Howard and that the Magic remain a viable option.
