Vujacic out with back spasms

Lakers guard Sasha Vujacic did not travel with the team on its flight to Houston Monday afternoon after suffering back spasms Monday morning.

``Right now I feel like I'm 90 years old, but tommorrow I'll feel 24 again,'' he said, in visible pain Monday afternoon.

With Jordan Farmar out until mid-February with a knee injury, Vujacic has become the Lakers primary back-up to point guard Derek Fisher.

He said he would try and join the team for part or all of its two-game road trip to Houston and San Antonio if he was feeling better. If he's unable to play though, Fisher --who has logged more than 40 minutes in six of the 11 games since Farmar's injury on December 19, could have to play even more minutes.
