The recovery time projects a January or February return to action for Howard. The 33-year-old center aggravated a piriformis muscle injury earlier this month. He hasn't suited up for the Wizards since Nov. 18.
Howard signed with Washington over the summer and has an opt-out on his contract after this season. He's averaging 12.8 points, 9.2 rebounds, and a career-low 0.4 blocks in nine games so far.
