Jennings was injured in the third quarter of Saturday night’s 101-86 loss at Milwaukee. Starting in place of Jennings, Detroit point guard D.J. Augustin scored a career-high 35 points. Greg Monroe had 21 points and 16 rebounds for the Pistons, who suffered their third straight road defeat.
Kentavious Caldwell-Pope added 16 and Andre Drummond had 14 for Detroit.
Augustin’s layup with 3:07 left brought Detroit to within four at 101-97, but Johnson followed by tipping in Kyle Lowry’s missed shot. Toronto had a chance to stretch its lead after Lowry rebounded a missed 3 by Jodie Meeks, but Johnson couldn’t convert a layup from Lowry’s long pass, leading to a fast-break dunk by Caldwell-Pope to make it 103-99 at 2:10.
After Toronto called timeout, DeRozan pushed the lead back to six with a pair of free throws. Meeks missed another 3 and DeRozan followed with a turnaround jumper on the baseline, putting the Raptors up 107-99 at 1:23.
Caldwell-Pope converted a four-point play with 15 seconds left as Detroit shaved the deficit to two, 112-110, but Terrence Ross answered with two free throws. Caldwell-Pope got two more attempts from 3-point range in the final seconds, but missed them both.
Toronto led 18-9 at 5:30 of the first, but Augustin scored nine points as the Pistons closed the quarter with a 16-8 spurt to cut the deficit to 26-25 after one. Augustin scored 11 in the first while Valanciunas had eight for the Raptors.
Monroe scored 13 points in the second, but the Raptors closed the quarter on a 9-3 run to lead 58-53 at halftime.
Toronto opened the third with six straight points to take their biggest lead of the game at that point. Valanciunas had eight points and five rebounds in the third as the Raptors took an 89-79 lead into the final quarter.
