The star pressed ahead with filming the first season of the cop show last year despite battling pancreatic cancer, and he was said to be in good spirits while training for the second outing of the program in March.
But online reports suggest Swayze will not be returning to the small screen as rogue FBI officer Charles Barker — because the show is on the verge of being dropped by A&E network executives.

Swayze was diagnosed with the fatal disease in early 2008 and was recently forced to deny rumors he was on his deathbed.
