Ilyasova aggravated a prior injury late in Sunday's win over Orlando, diving into the front row and hitting his hip on the basket standard to save a defensive rebound. The play was a critical one, as Monta Ellis hit a 3-pointer on the ensuing possession to put the Bucks up by four with 13 seconds to play.
"He's banged up pretty good," Bucks coach Jim Boylan said. "He still has some swelling in his hip. He's been getting treatment,, so we'll see where he is.
"Doubtful for tomorrow also (at Atlanta), so he'll probably stay behind and get some more treatment. We'll see if he can come down to Indiana (on Friday)."
With Ilyasova out, Bucks coach Jim Boylan is opting to go with a big front court, starting Samuel Dalembert in his place.
"I want to keep Ekpe in his role," Boylan said. "When you lose somebody I always believe you just stick somebody in and keep as many guys in their comfort zones as possible.
"So I'm putting Sam in there with Larry (Sanders). We start with a big team, we'll see where that takes us. One of our issues has been scoring in the paint, hopefully with two bigger guys out there maybe we can address some of that. We'll start with those guys and see where it goes."
Luc Richard Mbah a Moute will miss his fifth straight game with turf toe and Marquis Daniels will start for the third straight game in his place.
The starting lineup of Brandon Jennings, Monta Ellis, Daniels, Dalembert and Larry Sanders will be Milwaukee's 16th different starting lineup of the season.
