By 2014, his right knee required a total knee replacement. Medical testing revealed he also had been riding with a completely torn ACL. Following surgery, Stevens stated that he developed an addiction to the prescription painkillers he was given, so he isolated himself for a week and went off the medication cold turkey, after which he felt that he finally began to fully recover from the surgery. Three months after the operation, he returned to racing, working horses in the morning, and accepted mounts for the 2014 Breeders' Cup. On November 22, he won his first race following his surgery, an allowance optional claiming race at Del Mar racetrack. He returned to graded stakes-winning form with a Grade II win in the Grade II Arcadia Handicap on January 31, 2015:53 and achieved his 5,000th North American win on February 13, 2015.
