Washington Wizards center Dwight Howard suffered a setback to his recovery from a gluteal injury on Sunday against the Portland Trail Blazers.
The team announced he would not play in the second half due to "aggravated gluteal soreness."
Howard scored two points and grabbed three rebounds in seven minutes before exiting.
Howard missed the preseason as well as the start of the season due to a sore buttocks, according to the Associated Press (h/t ESPN.com), an injury stemming from his traveling to China for promotional appearances.
