Spoelstra met with Bosh Monday morning and later said that the All-Star will continue to rehab his abdominal strain.
"He's doing some work, but he won't be joining us (on Tuesday)," Spoelstra said following the Heat's practice on Monday. "He's not even near any court work right now."
The Heat tied up the Eastern Conference semifinals series with the Pacers 2-2 and have been without Bosh since Game 1 when he pulled a muscle in his abdomen on a dunk attempt.
When asked if Bosh could be ready for a potential Game 7 against the Pacers, which is slated for Saturday, Spoelstra wasn't willing to commit.
"It's too early to tell," Spoelstra said.
Bosh did not travel with the team to Indianapolis for Games 3 and 4. He has been receiving treatment in Miami since the injury that occurred eight days ago.
Bosh had been averaging 14.7 points and 6.8 rebounds in the playoffs before leaving Game 1 in the second quarter.
"We're trying to figure ourselves out on the fly with Chris out," Spoelstra said. "It's changed the dynamic of the team."
Heat forward Udonis Haslem stepped up in Game 4 on Sunday with 14 points and key shots down the stretch. Prior to Sunday, none of the Heat's power forwards or centers had scored more than 10 points in Bosh's absence.
Spoelstra was encouraged that Bosh was in good spirits on Monday morning.
"I just like seeing him. He had a smile on his face," Spoelstra said.
