Iverson missed 16 games from Feb. 27-March 28. He returned for the past three games and averaged 7.7 points and 2.7 assists in nearly 19 minutes. He complained about his role as a reserve.
The Pistons began Friday as the seventh-seeded team in the Eastern Conference.
They lead Chicago by a half game and Charlotte by two with less than two weeks left in the regular season.
Detroit plays today in Philadelphia, where Iverson was an MVP. The 76ers traded him two years ago to Denver. The Nuggets then dealt him to the Pistons for Chauncey Billups in November.
HEAT: Miami had three key players injured in a 5-minute span in the second half of Friday's game against Charlotte.
Forward Udonis Haslem cut his right thumb on the backboard; forward Michael Beasley twisted his right ankle; and center Jermaine O'Neal also came up lame with an apparent ankle injury.
KNICKS: Rookie Danilo Gallinari will have back surgery next week and is expected to make a full recovery in six to eight weeks.
The Knicks said Gallinari will have surgery Tuesday by an orthopedic spine specialist.
RAPTORS: Signed guard Quincy Douby to a second 10-day contract and reassigned rookie Nathan Jawai to the Idaho Stampede of the NBA Development League.
