At 34 years old, Travis Kelce knows he's nearing the end of his NFL career.

The Kansas City Chiefs tight end opened up about the subject of retirement in an interview with WSJ Magazine.

During that conversation, Kelce revealed that retirement is constantly on his mind and that it's something he thinks about "more than anyone could ever imagine."

According to Kelce, he's undergone 10 surgeries in his football career, and the pain from those surgeries still hasn't gone away.

"That's the only thing I've never really been open about, the discomfort. The pain," Kelce said. "The lingering injuries -- the 10 surgeries I've had that I still feel every single surgery to this day."

Kelce was a third-round pick of the Chiefs back in 2013.
