The Chicago Bulls and San Antonio Spurs are the leading contenders to sign Pau Gasol.

Gasol is giving strong consideration to signing with the Spurs despite their limited cap situation in case the Bulls can't agree upon a sign-and-trade deal involving Carlos Boozer.

The Los Angeles Lakers are reluctant to take on the contract of Boozer unless they receive an asset back from the Bulls.

The Oklahoma City Thunder have a $6.5 million trade exception that expires Friday night at 11:59 p.m., that they hoped to use in their own sign-and-trade with the Lakers.

The New York Knicks appear to be out of contention as well.
