Oden was seen in the locker room pregame with an ice pack on his left knee before going through a pregame workout.
"He's been working very diligently," Spoelstra said. "He's getting stronger, getting healthier. He's getting his core right, everything without skipping steps. We're very patient with it. He's been great about it."
Oden signed a one-year contract with the Heat this offseason. He has undergone multiple operations over the past four years on both knees, including three microfracture surgeries. In March 2012, he was waived by the Portland Trail Blazers, the team that selected him No. 1 overall in the 2007 draft.
Oden said he's fine with the Heat practicing patience with the center.
"It's a plan to keep me playing," he said. "That's the thing. I don't want to just get out there and then get injured again. My thing is to make sure I can go out there and keep playing games. That's the plan, and we're sticking to it."
As for free agent Andrew Bynum, Riley commented on the speculation that the Heat might be a landing spot for the center, who was waived by the Chicago Bulls recently.
"It's all speculation," Riley said. "That's all it is. There will be a tremendous amount of research (on free agents). There's nothing going at all. There's nothing happening at all with that situation."
