The Miami Heat are waiving forward Henry Walker, league sources told RealGM.

If Walker clears waivers, a return to the Heat is still possible.

Through the NBA Development League, Walker earned a call up to the Heat last season, a miraculous perseverance to turn a fleeting career into a comeback story.

Walker averaged 7.3 points, 3.4 rebounds and 1.1 assists in 24 games for the Heat. The 6-foot-6 stretch shooter shot 34.1 percent from three-point range in over five attempts per game.

Walker, 27, has played five NBA seasons for Boston, New York and Miami.
