UPDATE: Yahoo Sports! is reporting that Derek Fisher will play his first game for the Oklahoma City Thunder against the Los Angeles Clippers tonight.

According to ESPN.com, Derek Fisher will sign with the Oklahoma City Thunder when he clears waivers today:

Derek Fisher and the Oklahoma City Thunder have agreed to terms on a rest-of-the-season contract that will be signed after Fisher clears waivers, according to sources close to the process.

Fisher is scheduled to clear waivers at 6 p.m. ET Wednesday and is already in Oklahoma City in anticipation of joining the Thunder, who beat out the Miami Heat to add Fisher for the playoffs.

The Thunder have roughly $3 million left of their mid-level exception and thus possessed the ability to outbid Miami by offering a portion of that amount to sign Fisher to a one-year deal.

The Lakers play the Thunder two more times this season. March 29th in Los Angeles, and April 22nd also in Los Angeles.

Fisher reached a buy-out agreement with the Houston Rockets after he was traded by the Los Angele Lakers for Jordan Hill.
