Pacers' forward Jermaine O'Neal sat out Indiana's regular-season opener against Washington on Wednesday night because of a hyperextended left knee.
O'Neal, a six-time All-Star, was hurt Oct. 8 when he collided with Shawne Williams during practice.
"Jermaine practiced today, but he's not ready to play," Pacers' coach Jim O' Brien said. "We expect him to play [Friday] against Miami."
Ike Diogu replaced O'Neal in the starting lineup.
Pacers center Troy Murphy also missed the game because of a strained left Achilles tendon. Williams sat out the first game of a three-game suspension for getting caught driving without a license.
