Earl Clark went from scoring 14 points all season (before Wednesday) to starting for the Lakers and guarding Kevin Durant on Friday.
The fourth-year forward got the nod from Lakers Coach Mike D'Antoni after Pau Gasol was not medically cleared to play against Oklahoma City.
Gasol will miss his third game because of a concussion. The Lakers' next game after Oklahoma City is Sunday against Cleveland. Gasol will be reevaluated before then.
Clark had 22 points and 13 rebounds in the Lakers' 108-105 loss Wednesday to San Antonio. He was active and agile, two traits the Lakers have lacked all season.
"Earl's on Durant," D'Antoni said. " 'Earl-sanity,' baby. His feet are good and he played well."
Metta World Peace has a minor groin injury and will start against the slower Serge Ibaka instead of Durant.
"We're trying to save him a few minutes off of Durant and not get in foul trouble," D'Antoni said of World Peace. "Earl's the best choice ... we think."
Clark was a throw-in from Orland...
