However, the former long-time WBC heavyweight champion is not ready to throw in the towel on his career just yet and begins another comeback attempt against little-known opponent Herndon on Friday night at Charles Koch Arena in Wichita.
Wilder is eager to reignite ambitions for a long overdue showdown with Joshua later in 2025 and will hope to roll back the years with an emphatic stoppage of his fellow American this evening.
However, a shock upset against a fighter with whom the majority of the boxing public will be unfamiliar would surely end those chances for good and leave him with no choice but to hang up the gloves.
Joshua will have a keen eye on proceedings no doubt as he continues to recover from elbow surgery that has delayed his comeback from that comprehensive defeat by IBF champion Daniel Dubois at Wembley last year.
