Chicago Bulls forward Bobby Portis is set to miss at least a month with a knee injury.
The third-season forward, a key component on the young Bulls squad, has been diagnosed with a sprained medial collateral ligament in his right knee.
Chicago put the timescale for Portis' return at four-to-six weeks.
Portis suffered the injury during the Bulls' 112-110 win over the Charlotte Hornets on Wednesday, a game that provided their first victory of the season.
He had been averaging 10.5 points and 10 rebounds per game over their first four games, his best performance a 20-11 line against the Philadelphia 76ers.
Portis joins Kris Dunn, Lauri Markkanen and Denzel Valentine on the Bulls' injured list.
Dunn suffered a similar injury on Monday and will also be out for four-to-six weeks, while Markkanen will not be back until November with an elbow injury and Valentine has an ankle problem.
