Wallace, who was examined by team doctors shortly before Sunday's game and cleared to play, scored 15 points with a rebound, steal and block in the Knicks' 121-100 victory.
The Pistons (3-11) have a front line featuring 6-foot-11 Greg Monroe and 6-11 Austin Daye with 6-10 Andre Drummond coming off of the bench, so the Knicks needed the 6-11 Wallace to counter their size.
With Wallace out on Friday, the Knicks were outrebounded, 49-30 by the Rockets in a 131-103 loss. They held their own against Detroit on Sunday and forced the Pistons into 19 turnovers.
Wallace, 38, has established himself as an important rotation piece for the 8-3 Knicks, averaging 7.5 points, 4.4 rebounds and one block in 15 minutes.
Kurt Thomas replaced Wallace in the rotation against Houston, pulling down just one rebound in 10 minutes, but did not play Sunday upon Wallace's return.
Marcus Camby, who did not play in the Knicks last two games, got off the bench to grab three rebounds in five minutes against the Pistons.
Woodson was hesitant to play Camby recently because of conditioning issues. The 38-year-old missed the entire preseason because of a calf injury.
