He is expected to miss between six to eight weeks, according to Bulls coach Tom Thibodeau.
"From what we heard, it went well," Thibodeau said of the surgery. "So we're encouraged by that, and now it's just a matter him going through his rehab."
Boozer injured the finger Saturday night during an unscheduled off-day, when he tripped over a bag in his home and fell.
"Had a successful surgery this morning. Now gonna attack my rehab," Boozer tweeted after the procedure.
Thibodeau is hopeful Boozer will be able to return to game action at about the eight-week mark, but isn't sure how quickly the veteran forward will heal.
"It could be anywhere from six, eight, 10 weeks, so once he gets his cast off and all that, his conditioning should be OK because he can run and do all that stuff, but then his hand, he has to show that he has the ability to take a hit and all that," Thibodeau said. "So, we're thinking six to eight weeks."
The Bulls open the preseason in Milwaukee Tuesday night against the Bucks.
