-- Turner Sports reporter Craig Sager said his cancer is no longer in remission.
This is the third time Sager has battled leukemia since he was first diagnosed with the disease in 2014.
In an interview that will air Tuesday on HBO's "Real Sports," Sager concedes he has a tough road ahead.
"I've already had two stem-cell transplants. Very rarely does somebody have a third," Sager said in an excerpt of the interview posted online. "So I have to maintain my strength, so I can go through this."
Sager previously received bone-marrow and stem-cell transplants from his son, Craig. He plans to continue his fight.
"Still kicking, still fighting. I haven't won the battle. It's not over yet, but I haven't lost it either," Sager told HBO. "There have been some victories and some setbacks. I still have to fight it, and I still have a lot of work to do."
Sager, 64, primarily works on Turner's broadcasts of the NBA and NCAA tournament. He has become a well-known fixture, thanks to his years of experience and colorful suits.
Despite the news, Sager is still scheduled to be part of Turner's "NBA on TNT" broadcasts through April, according to Yahoo! Sports.
