An actor who has appeared in the HBO drama series "Game of Thrones" has been diagnosed with pancreatic cancer, according to The Hollywood Reporter.

Wilko Johnson, who plays Ser Ilyn Payne on the HBO show, is also known as the guitarist for the 1970s U.K. band Dr. Feelgood. His manager, Robert Hoy, announced his illness on Johnson’s Facebook page earlier this week.

Hoy wrote that Johnson has "chosen not to receive any chemotherapy." Johnson isn’t yet suffering physical effects, Hoy added.

"He has just set off on a trip to Japan; on his return we plan to complete a new CD, make a short tour of France, then give a series of farewell gigs in the U.K. There is also a live DVD in the pipeline, filmed on the last U.K. tour," he wrote.
