All-Star DeMar DeRozan exited the Chicago Bulls' 100-91 defeat to the Orlando Magic with a right hip injury that he revealed has been bothering him for over a month.
DeRozan exited with 1:02 remaining in the fourth quarter, having scored 19 points on eight-of-20 shooting across 36 minutes in the loss that leaves the Bulls with a 26-31 record.
The loss was Chicago's fourth in a row and marked the fourth straight game that DeRozan has not reached 20 points.
The Bulls small forward missed last Monday's game against the Memphis Grizzlies with the same hip issue and is due to undergo further testing on the problem on Tuesday.
"It was bothering me the whole game," DeRozan told reporters. "I just felt it. I didn't want to risk nothing. Hurting it anymore, what it was or anything.
"Just the accumulation of what it's been, attempting to play on it."
DeRozan, who was selected for the upcoming All-Star Game, is averaging 25.4 points, 4.7 rebounds and 5.1 assists this season.
"It's too early to say. I always take everything day by day," DeRozan said, when asked if he will rule himself out of the All-Star Game.
"Get some rest, wake up, see how I feel tomorrow, get it checked out, get a better idea of what exactly it is, have a better idea of how to treat it and how to deal with it.
"It's something that I've been playing on for the last month and a half, just never said anything. Just want to get it right, especially going to the break."
