The children of TNT sideline reporter Craig Sager report that their father will begin treatment for acute leukemia and will miss the NBA playoffs.

Craig Sager II announced the news on Twitter on Thursday night, saying the family had gotten the news just a few days after being told he did not have cancer.

From Sager’s daughter:

Sager is a mainstay of NBA telecasts with his ridiculously, wonderfully wild outfits and the playoffs just won’t be the same without him. But, as his son points out, he’ll have time to dream up some new concoctions.
