Despite Jamison's injury, a source said, "He's going to gut it out." Jamison is planning to play Monday at Golden State, the source said.
An MRI revealed a sprained wrist, the Lakers said in a statement Saturday. His status will be day to day and he will be reevaluated at the conclusion of the season.
The injury appeared to happen when Jamison's dunk attempt with 1:10 remaining in the third quarter was blocked by the Wizards' Kevin Seraphin.
Jamison finished the game with 11 points on 5-of-9 shooting along with seven rebounds. He did not play in the fourth quarter.
The 15-year veteran is averaging 9.2 points and 4.7 rebounds this season.
The timing of Jamison's injury speaks to the revolving-door nature of the Lakers' roster this season as it happened the same night Pau Gasol returned to the lineup after missing 20 straight games because of a torn plantar fascia in his right foot. Gasol finished with four points on 2-of-10 shooting and eight rebounds in 21 minutes.
