MIAMI -- An MRI on Monday showed Chris Bosh suffered an abdominal strain and the Miami Heat have ruled him out indefinitely. The team is operating under the belief he'll miss the rest of the playoff series with the Indiana Pacers.

The injury occurred on a dunk during the first half of the Heat's 95-86 Game 1 win on Sunday.

"This season has to be extended for me to play again. That's what's on my mind," Bosh said. "We started treatments and it's a process. We'll see how my body responds."

The fact that the team didn't put a timetable on Bosh's return suggests that his strain is not mild. But the team hasn't ruled him out for the season, so his injury likely falls within the moderate category of abdominal strains. Typically, players who have suffered this type of injury have been out from two to four weeks.

"We're moving on as if he's not going to return in this series but we'll see," LeBron James said.

Heat coach Erik Spoelstra said the team was encouraged by the MRI results, which showed that Bosh did not suffer a complete tear that would require surgery. Earlier this season Mike Miller suffered a similar injury, a sports hernia, that did need surgery.
