The veteran guard was waived by the team during the last round of roster cuts before Sunday's season opener against the Dallas Mavericks. House returned to Miami last season after spending the first three years of his NBA career with Miami.
House averaged 6.5 points, 1.6 rebounds and 1.1 assists in 56 games off the bench in South Beach. The 11-year veteran out of Arizona State was a member of the Boston Celtics squad that won the league title in 2008.
Among those that Pat Riley passed over for cuts were veteran big man Eddy Curry and rookies Mickell Gladness and Terrel Harris.
Without House, the Heat will be particularly thin in the backcourt, with only third-year guard Mario Chalmers and rookie Norris Cole to handle the ball alongside Dwyane Wade. House's absence also leaves Wade's backup minutes entrusted to the rookie Harris and longtime sharpshooter Mike Miller, who played in only 41 games last season due to a series of injuries.
Known for his ability to score in bunches and hit shots from the perimeter, House should have little trouble finding employment elsewhere in the NBA and would be a welcome addition to a number of teams in need of guard depth, including the Celtics, the Los Angeles Lakers and the New York Knicks.
