Thunder, Heat Frontrunners For Derek Fisher

3:42pm: Fisher is in "advanced negotiations" to sign with the Thunder after he clears waivers, according to ESPN.com's Marc Stein. Oklahoma City has the advantage over Miami because the Thunder have more financial flexibility and can offer Fisher a larger role, says Stein.

3:03pm: Sources close to Fisher expect him to sign with the Thunder if he clears waivers, according to Sam Amick of SI.com (Twitter link).

12:48pm: The Spurs are still expecting to sign Mills and don't plan to talk to Fisher, sources tell Adrian Wojnarowski of Yahoo! Sports (Twitter link).

12:08pm: The Celtics and Bulls aren't interested in Fisher, according to Ken Berger of CBS Sports (via Twitter). Berger adds that Fisher is expected to discuss "ideas and concepts" with the Spurs, Heat, and Thunder.

8:05am: The Thunder and Heat have emerged as the favorites to sign Derek Fisher, reports ESPN.com's Marc Stein. Fisher, who was bought out by the Rockets, is expected to clear waivers tomorrow.

The Spurs are also believed to have some interest in Fisher, but San Antonio is still hopeful about completing a deal with Patrick Mills. Stein adds that signing with Chicago is something that "strongly interests" Fisher, but the Bulls are focused on signing a big man, possibly Ronny Turiaf.

According to Stein, there are a couple factors that could work in the Thunder's favor in the race for Fisher: The veteran point guard now shares an agent with Kevin Durant, and Oklahoma City has a good chance to face Fisher's old team in the Western Conference playoffs. Unlike the Heat, however, the Thunder don't have an open roster spot, so they'd need to waive someone to clear room for Fisher.

Ramona Shelburne of ESPNLosAngeles.com reports that the Rockets allowed Fisher's agent to speak to "about six teams" during buyout negotiations to gauge interest. Knowing there were contending teams interested in bringing him aboard, the 37-year-old felt comfortable giving up the final year of his contract (Twitter links).
