ORLANDO, Fla. — Detroit Pistons guard Chauncey Billups won't play in Game 4 of the Eastern Conference semifinals against the Orlando Magic today.

Pistons coach Flip Saunders says Billups wouldn't be effective because of a sore hamstring. The All-Star strained it on Thursday after getting tied up under the basket with an Orlando player.

With Billups out, the Pistons are activating guards Lindsey Hunter and Juan Dixon. Rookie Rodney Stuckey was effective in Game 3 and is expected to start in place of Billups, who is third in career playoff scoring for the franchise.
