According to @LakersReporter (Mike Trudell), via Twitter:

Phil Jackson said after practice that Pau Gasol will not play tomorrow, but is possible for Sunday.

Phil: "We're not worried about (Gasol's hamstring) we're just taking it real slow. Don't you worry about it."

Fortunately, the Lakers depth (see: Pills, Crazy) allows the Lakers to take it slow with Gasol, play it safe, and still be strong in the present:

Jackson added that Odom and Artest would likely both spend time guarding Dirk.

Ric Bucher asked Phil if Artest's versatility helps the Lakers be cautious with injuries like Gasol's: "Without a doubt."
