The Chicago Bulls have confirmed that Jimmy Butler is expected to be out for the next three-to-four weeks with a strained left knee injury.
The prognosis means the shooting guard will be unable to take his place in the 2016 NBA All-Star game in Toronto this weekend.
Taking Butler's spot in the prestigious game will be Bulls teammate, Pau Gasol. The Spanish veteran took to social media to reveal the news.

Cleveland Cavaliers point guard Kyrie Irving had appeared to be next in line, having been the player to receive the most fan votes without being selected as a reserve by NBA coaches.
However, NBA commissioner Adam Silver - the man responsible for selecting Butler's replacement, opted to keep things in Chicago. Gasol will now be making his sixth All-Star appearance.
As for Butler, his absence beyond the All-Star game will come as a big blow for the Bulls. The 26-year-old has been averaging 22.4 points this season and has taken on increased responsibility in the team's offense under Fred Hoiberg.
With the Bulls having already been struggling in recent weeks -they are 3-7 over the past 10 games and has slipped to seven seed in the East - being without Butler for potentially the next 10 games is far from ideal.
A four-week spell on the sidelines would put the Texas-native in line for a return against the San Antonio Spurs on March 10. Unfortunately for the Bulls, they face Eastern Conference rivals the Atlanta Hawks (twice), Cleveland Cavaliers, Toronto Raptors and Miami Heat before that.
