Houston Rockets center Dwight Howardsaid on Sunday that he will miss 6-8 weeks with a right knee injury, though a MRI showed no signs of structural damage.

On Wednesday, the Rockets announced Howard had a bone marrow aspirate injection into the knee and would begin rehab immediately. The team also said Howard would be re-evaluated in approximately four weeks.

Howard also told reporters that the most important thing for him was to get into game shape for the playoffs.

Howard, a three-time NBA Defensive Player of the Year, last played on Jan. 23 against the Phoenix Suns. He left the game with a sprained right ankle and later reported swelling in his right knee. Howard was diagnosed with edema, or swelling due to an excess of fluids, and was initially ruled out for at least one month.
