The reigning two-time scoring champion might not be at full strength when the Rockets try for another rare win over the Spurs at the Toyota Center.
McGrady scored 13 points in the final minute to help Houston wipe out a 10-point deficit in a dramatic 81-80 home win over San Antonio on Dec. 9. He hit the game-winning 3-pointer with 1.7 seconds left, finishing with 33 points as the Rockets ended a seven-game losing streak in the series.
Houston has lost 21 of the last 24 meetings with the Spurs.
McGrady, who has averaged 28.3 points in his last three games against San Antonio, comes into Saturday’s game with several injuries.
After entering Houston’s 94-85 overtime win over New Jersey on Thursday with an injured left thumb and bruised left big toe, McGrady exited briefly in the fourth quarter with a strained left quadriceps. He returned quickly, but finished the game with only 18 points.
McGrady had averaged 29.3 points in his previous nine games.
“I really couldn’t do anything,” McGrady said. “This injury I’m concerned about. I’m concerned about it carrying over to Saturday night’s game” against San Antonio.”
Bob Sura scored a career-high 35 points as the Rockets matched a season-best three-game winning streak and won for the sixth time in eight games overall. Houston is also two games above .500 for the first time this season.
Sura, playing on a knee that had been drained of fluid Tuesday, hit a career-high six 3-pointers, including the game clincher with 1:02 left in overtime.
“I knew I had to step up,” said Sura, who had totaled 20 points in his previous two games. “I’m hanging in there. I’ll fight through it as best I can and try to help our team.”
The Rockets are shooting 52 percent (32-for-62) from beyond the arc in their last three games. They are also scoring 101.6 points in their last 14 games after averaging just 87 in their first 22.
Coming in off a 98-85 home win over Dallas on Friday, the Spurs are allowing a league-low 86 points per game. Tim Duncan had 25 points, and Manu Ginobili and Tony Parker added 22 and 12, respectively, as San Antonio won for the 10th time in 12 games.
The Spurs have shot 50 percent (183-for-367) over their last five games. They were 38-of-76 against the Mavericks on Friday.
San Antonio is 8-2 in the back end of back-to-back games this season.
