The Rockets will have to face the NBA's defending champions without Tracy McGrady.

McGrady, the league's second-leading scorer, is expected to miss Friday night's showdown against the San Antonio Spurs with a sprained right elbow. He remains listed as day-to-day after an MRI revealed no tendon or ligament damage.

The Rockets' seven-time All-Star left Wednesday's game in the second quarter after his right arm was bent backward reaching for a loose ball in front of the Lakers' Luke Walton.

"The doctors say it will be a week, but I don't know; we'll see," McGrady said after Wednesday's loss to the Los Angeles Lakers. "I will see how it feels."
