EL SEGUNDO, Calif. -- Lakers reserve guard Sasha Vujacic stayed after practice Saturday hoisting up left-handed free throws, but the activity wasn't signifying a late entry by Vujacic into Pau Gasol's and Kobe Bryant's season-long southpaw shooting competition.
It was signifying "The Machine" needs some repair.
Vujacic is expected to be out of the lineup at least two weeks after suffering a right shoulder sprain in the second half of Thursday's 87-86 loss to the Celtics when he ran into a screen set by Boston's 6-foot-10, 280-pound center Kendrick Perkins and fell to the floor.
"I felt it immediately," Vujacic said. "It kind of moved around and I kind of moved it back and then that shock of pain [made me] fall down. ... It's pretty painful."
Vujacic, who increased his season averages of 2.5 points, 1.1 rebounds and 0.6 assists to 4.4, 2.0 and 1.8 in the five games Bryant sat out because of a left ankle and tendon injury, stayed in Thursday's game after the collision and attempted a 3-pointer with 3:56 remaining. He said his condition has since declined.
"After the game it got even worse and worse and the next day was terrible," Vujacic said.
The sixth-year guard said he cannot stretch the shoulder. He should be wearing a sling to support it but doesn't like it. He is receiving Ultrasound and laser treatment from Lakers trainer Gary Vitti.
"We're definitely taking it one step at a time," Vujacic said. "It's still very sensitive and it's inflamed."
