Detroit's Richard Hamilton (groin) missed his third straight game, and Antonio McDyess sat out after injuring his ribs Monday in a win over Orlando.
Rookie Brook Lopez led the Nets with 23 points and 12 rebounds in their lowest-scoring game of the season. Devin Harris added 19 points.
Harris' three-point play made it 75-70 with 3:45 left, and Yi Jianlian followed with a hook to make it a three-point game.
Iverson, though, hit a pair of high-arcing jumpers and Detroit held on.
