LONDON — Dwyane Wade's recovery from knee surgery is right on schedule, and the All-Star guard expects to be ready to go when the Miami Heat open the defense of their NBA championship.

The way he was walking around London on Wednesday, it would have been tough to guess he had surgery a month ago.

"I feel good. Rehab is going very well," Wade said. "I'm happy with it. I'm more encouraged than I was, obviously, when I knew I had to get surgery. So I'm happy."

Wade was in London making a promotional appearance at NBA House for Gatorade, one of his longtime sponsors, and its sports science institute. If the knee surgery wasn't needed, Wade would have been in London for another reason — playing in the Olympics with the U.S. squad. He helped the team win a bronze at the 2004 Athens Games and gold at the 2008 Beijing Olympics.

He didn't hesitate when asked if he thought there was a chance his Heat teammate LeBron James and the rest of the U.S. men wouldn't win gold.

"No," Wade said. "No. Simple as that."
