Washington Wizards center Dwight Howard has suffered a minor setback in his recovery.
Coach Scott Brooks told reporters on Tuesday that Howard has tweaked his hamstring.
Howard has been out since undergoing a spinal procedure in November and there is no timetable for his return. He had been participating in non-contact drills.
"Don't know when he's going to come back," Brooks said.
"Obviously, the season is winding down. But he's moving around pretty good today."
The 32-year-old big man is an eight-time All-Star and has averaged 12.8 points and 9.2 rebounds per game in just nine appearances in 2018-19.
The Wizards are 26-37 and sit in 11th in the Eastern Conference standings.
Washington have gone 2-3 since the All-Star break and will face the Dallas Mavericks on Wednesday.
