MILWAUKEE (AP) -- Andrew Bogut had 25 points and 17 rebounds, and the Milwaukee Bucks knocked off another Eastern Conference heavyweight, making a fourth-quarter comeback to beat the Boston Celtics 86-84 on Tuesday night.

Carlos Delfino added 19 points for Milwaukee in a game that featured a heated on-court confrontation between Bucks rookie Brandon Jennings and the Celtics' Glen Davis midway through the fourth quarter.

The Bucks went on an 18-9 run from there, grabbing an 86-79 lead on Jennings' floating jumper in the lane with 2:42 left.

Rajon Rondo converted a three-point play, then Kevin Garnett hit a jumper to cut the lead to two with 53 seconds left. Paul Pierce missed a potential game-tying shot just before the final horn. Rondo had 20 points for Boston.
