Heat forward Mike Miller underwent surgery to repair a torn ligament and fracture on his right thumb on Friday.

Miller is expected to be out until January.

He suffered the injury during practice on Wednesday when his hand got caught in a teammate's jersey.

"It's good to finally have a resolution about his injury, and now a course of action to make it better," Heat coach Erik Spoelstra said.

"I feel bad for Mike. I know how badly he wanted to get this season started in the right way. He's down right now, but it's the unfortunate reality of our profession. I knew this season wasn't going to be easy."
