Bulls coach Fred Hoiberg said Rondo has a cast and will be re-evaluated in 7-10 days.
The Bulls said Rondo’s injury will not require surgery, but a source told ESPN’s Chris Haynes that the injury was “pretty serious” and his possible return depends on how long the Bulls’ can extend their postseason run.
Jerian Grant will start in Rondo’s place for Game 3 on Friday night in Chicago. The Bulls have a 2-0 lead in the best-of-7 series against the top-seeded Celtics.
Hoiberg said Rondo finished the game after suffering the injury in the third quarter of Game 2. Rondo had 11 points, 14 assists, nine rebounds and five steals — just one rebound shy of becoming the team’s first player since Scottie Pippen (1997) to get a postseason triple-double.
The 14 assists tied a Bulls playoff record.
Rondo averaged 11.5 points and 10 assists in the Bulls’ two victories over the Celtics.
