Boston Celtics power forward Marcus Morris disclosed to reporters that his aching knee won’t need surgery. That’s as far as he could tell, however, according to Celtics beat writer Scott Souza.

Morris has missed the Celtics last three games with soreness in his left knee. Morris’ first year in Boston is being derailed by his problematic knees. Out of the 30 games the Celtics have played so far this season, Morris has appeared in just 16. The 28-year-old Kansas product wasn’t able to suit up for Boston in its first eight games of the campaign due to an issue to his right knee.

The Celtics have not yet released a definite timetable for Morris’ recovery and return, but the power forward is looking forward to making a return either on Dec. 23 against the Chicago Bulls or on Christmas Day when they face the Washington Wizards, per Gary Washburn of the Boston Globe.

Of course, Morris’ optimism isn’t the final indicator of his status, but at least he’s feeling better about his knee.

The floor-spacing big man is averaging 12.1 points and 5.5 rebounds per game, while shooting 32.8 percent from long range.

For the meantime, the Celtics will see an increased usage for Daniel Theis and Aron Baynes while giving Guerschon Yabusele some extra run on the floor while Morris is out.
