Nowitzki said he's hoping to be out only one or two weeks. The regular season ends three weeks from Wednesday.
"I'm trying to see the positive and it could've been a lot worse," Nowitzki said, wearing a protective boot on his left ankle. "It could've been a season-ending injury or even career-ending."
He said the ankle and knee are both still stiff. He's trying to reduce swelling by putting them in ice every two hours, even when he sleeps. Doctors will check him out again Tuesday, then set a rehabilitation plan.
