Miami Heat head coach Erik Spoelstra stated Monday that forward Chris Bosh, who hasn't played since Game 1 of the Eastern Conference semifinals against the Indiana Pacers due to a strained lower abdominal muscle, is "day-to-day."

Game 5 of the Eastern Conference finals against the Boston Celtics is Wednesday at AmericanAirlines Arena.

"The reality is that this is not a normal situation. (The situation) is heightened and it is extreme. We have to be judicious in our evaluations," Spoelstra said.

Bosh suffered the injury shortly before halftime of the Eastern Conference semifinal opener against the Pacers.

Bosh dunked over Pacers center Roy Hibbert and drew the foul with 1:06 remaining in the second quarter, but landed awkwardly and remained on the floor momentarily. He made the free throw, cutting Miami's deficit to 48-42, and contested Hibbert's miss on Indiana's next possession before departing for the locker room.

In six playoff games, Bosh has averaged 14.7 points and 6.8 rebounds. He averaged 18.0 points, 7.9 rebounds and 1.8 assists in 57 regular-season games.

"He's making significant progress," Spoelstra said. "Each day will be a new evaluation and we'll go from there."
