Before the game against the Nuggets, houston faces road matchups with Golden State (18-2) and Sacramento (11-11).
Rockets coach Kevin McHale said on Saturday that Howard "won't be back anytime soon."
Over 10 games this season, the 6-foot-11, 265-pound center was averaging 18.8 points and 11.3 rebounds. With Howard out of the lineup, the Rockets have gone 7-2 and are riding a four-game winning streak.
Howard said Wednesday that he's feeling a lot better than he was a couple of weeks ago.
“Nobody has really talked to me about it because they understand that injury, you can’t put a timetable on,” Howard said. “I’m just happy that I’m in better shape than I was a couple weeks ago. I feel a lot better than a couple week ago. Hopefully, everything will go well for Saturday.
“The problem was my cartilage was wearing down and has been wearing down because I’ve been playing basketball for a very long time. When you had the bone rubbing on bone, it brings a lot of pain. Every step, every movement I would make it was just a lot of pain. I wasn’t going to put myself and my teammates through that by trying to play through that. It was something that had to go away for me to be where I wanted to be as a player, be what my teammates needed me to be every night.”
Houston, which has also dealt with injuries to multiple other players, is 16-4 and in fourth place in the Western Conference.
