Craig Sager Reveals Leukemia No Longer In Remission

NEW YORK (CBSNewYork) -- Colorful NBA sideline reporter Craig Sager is dealing with another setback with his fight against leukemia.

The 64-year-old TNT reporter told HBO's "Real Sports" that he's now entering "unchartered waters" after doctors told him in February that his cancer was no longer in remission.

"I've already had two stem cell transplants, very rarely does somebody have a third," Sager said. "So I have to maintain my strength so I can go through this."

Sager was originally diagnosed with leukemia in April 2014, undergoing chemotherapy and a bone-marrow transplant from his son. He returned to his broadcast duties in March 2015, but had to step away once again when his leukemia returned.

Sager returned for the NBA's Opening Night in October, and what millions of NBA fans were waiting for, his first interview of San Antonio Spurs head coach Gregg Popovich in December.

Despite the latest setback, Sager said he's "still kicking, still fighting."

"I haven't won the battle, it's not over yet, but I haven't lost it either," Sager told "Real Sports." "There's been some victories and some setbacks, and I still have to fight it and I still have a lot of work to do."

A Turner Sports spokesperson told Yahoo! Sports that Sager will continue his NBA broadcast schedule with TNT.
