Arizona Cardinals head coach Bruce Arians is the fearless leader of his organization, but he doesn’t have a specific timeline on how long he’ll remain on the sidelines.

Arians is entering his fifth season as the Cardinals’ head coach, but wouldn’t commit past the 2017 campaign, citing his ongoing health concerns.

“We’ll reevaluate it at the end of next year, and hopefully we’ll be ready for another one,” Arians said to ESPN’s Josh Weinfuss.

Arians has successfully fended off prostate cancer, but recently had to fight through numerous other health scares.

The 64-year-old underwent surgery in February to remove a cancerous part of his kidney after doctors found the afflicted area in December.

After battling through a series of tests and procedures, Arians doesn’t want the 2017 season to be his last.

“I hope not,” Arians said. “That’s going to mean I’m not healthy.”
