Chris Bosh is expected to play more minutes in Game 6 than he did in Game 5.
Bosh returned to action for the first time in three weeks, playing 14 minutes in Miami's 94-90 loss to the Celtics.
"I'm still going through that thought process," Erik Spoelstra said after the Heat wrapped up practice in Miami before traveling to Boston. "But I think he'll be able to handle a bigger load of minutes, and it'll be based more on how he'll feel during the game."
Bosh suffered a strained abdominal muscle on May 13 in Game 1 of the conference semifinals against Indiana.
