Ricky Rubio out indefinitely

— -- MIAMI -- Minnesota Timberwolves point guard Ricky Rubio is out indefinitely because of a badly sprained left ankle.

Rubio could be sidelined for seven to eight weeks, according to USA Today.

He was injured in his team's game at Orlando on Friday night. An MRI exam performed on Saturday confirmed the severity of the sprain.

"He's in good spirits," Saunders said before Minnesota faced the Heat, not long after Rubio hobbled into the arena on crutches with a boot protecting his ankle. "He feels good. Anyone who knows Ricky, he went through his knee situation a few years ago, he's an extremely hard worker. So he'll get back. If anyone is going to get back as soon as they can, he'd be a guy that would."

Rubio agreed to a $55 million, four-year contract extension with the Timberwolves on Oct. 31. He entered Saturday as one of only four players with at least 50 assists this season.

With Rubio out, the Timberwolves will rely more on Mo Williams at the point, though Saunders said he's leery of playing the veteran more than 25 minutes a night. Rookie Zach LaVine, who logged a total of 13 minutes in Minnesota's five games entering Saturday, also will become a bigger part of the rotation.

Saunders said he expects there will be a substantial learning curve for LaVine.

"I'm sure my hair will get grayer and I'll lose a few more hairs over the course of things," Saunders said.

Rubio is averaging 9.4 points and 10 assists this season.

Minnesota will remain in Miami through Monday, which means Rubio will have a couple extra days to potentially see swelling in the ankle subside before he flies home.

"He can't put any weight on it to get any kind of weight-bearing X-ray," Saunders said. "Two weeks, we'll be able to look at it and then we'll know."
