Washington Wizards center Dwight Howard suffered a setback in his attempted return from a back injury.
According to Ben Standig of NBC Sports Washington, Wizards head coach Scott Brooks said that Howard suffered a hamstring injury, and it remains uncertain when he will return to action.
The 33-year-old veteran has appeared in just nine games this season, and he hasn't appeared in a game since November due to the back ailment. In nine games, Howard is averaging 12.8 points and 9.2 rebounds.
During the offseason, the Charlotte Hornets traded Howard to the Brooklyn Nets, and the Nets subsequently waived Howard.
