The Miami Heat and Oklahoma City Thunder have emerged as the early leaders in the race to sign veteran guard Derek Fisher after he clears waivers Wednesday, according to sources close to the situation.

With the Chicago Bulls needing another big man more than another guard and the San Antonio Spurs still hopeful they can complete the signing of guard Patrick Mills by week’s end, sources told ESPN.com that Miami and Oklahoma City are the current front-runners to land Fisher, who was formally waived Monday night by the Houston Rockets.
