Per Sean Highkin of Bleacher Report, the NBA announced Tuesday that Gasol would take Butler's spot in the midseason superstar showcase.
An erratic season for the Bulls took a bad turn Tuesday when the team announced Butler would miss three to four weeks with a strained left knee. The 26-year-old suffered the injury during a game against the Denver Nuggets on February 5.
Butler, who was named a reserve on the Eastern Conference roster for the second straight season, leads the Bulls in scoring average (22.4) and ranks second in player-efficiency rating (22.0) and assists per game (4.3), per Basketball-Reference.com.
Even though Gasol didn't make the initial cut of All-Stars, the 35-year-old certainly deserves his spot on the roster in the midst of one of his best seasons, per ESPN Stats & Info:
Gasol will join a group of big men on the Eastern Conference roster that includes the Miami Heat's Chris Bosh and the Atlanta Hawks' Paul Millsap. This will be his sixth All-Star Game appearance in his 15-year NBA career.
While Butler's scoring prowess will be missed on Sunday against a loaded Western Conference roster, Gasol fits in nicely because he gives head coach Tyronn Lue more size to use against players like Draymond Green, DeMarcus Cousins and Anthony Davis.
