The Chicago Bulls will be without their floor general, Rajon Rondo, indefinitely after he suffered a fracture in his right thumb while playing in Game 2 of their first-round series against the Boston Celtics, the team announced on Friday.

Rondo underwent a subsequent exam following the game and his x-rays confirmed the fracture. Surgery will not be needed to treat his injury.

The fracture was considered “pretty serious” and he will be re-evaluated in 7-to-10 days, per Haynes. His potential return would depend on how long or far the Bulls can go into the postseason.

Chicago had just started to get back into a groove with the 6-foot-1 point man, jelling with the other two All-Stars in Jimmy Butler and Dwyane Wade.

This is a major hit for the team, which will go back to Jerian Grant to run the show in his absence.

While Grant only averaged 5.9 points and 1.9 assists in the season, he's done well when replacing Rondo, putting up a 17-point, 11-assist gem in his last starting performance against the Orlando Magic on April 10.

Rondo is averaging 11.5 points, 10 assists, and 3.5 steals per game in the series. The Bulls lead 2-0 heading into tonight's 7:00 p.m. ET Game 3 matchup at the United Center.
