Chris Bosh could be back with the Miami Heart for Game 5 of the Eastern Conference finals. Unless Bosh suffers a setback in workouts leading up Tuesday night’s game against the Boston Celtics, the Heat hope to activate the All-Star, ESPN.com reported. Bosh has missed nine playoff games since he suffered an abdominal strain in the opener of an Eastern Conference semifinal series against the Indiana Pacers. At the time, the team indicated that it was optimistic he could return for the NBA Finals should Miami advance. Bosh and the team would not comment on his availability for Tuesday night after the Heat’s 93-91 overtime loss Sunday night in Boston that tied the series at 2-2. For the past week, Bosh has been working out on the court. He joined teammates on the floor during practices while the series was in Boston. Bosh would be a welcome addition to the Heat, which has used three starting centers with Bosh sidelined and had difficulty containing Boston's Kevin Garnett.
