The 2018 Pro Bowl running back celebrated the four-year anniversary of the day doctors informed him he was cancer-free:
While still in college, Conner announced in December 2015 he had been diagnosed with Hodgkin lymphoma.
He had been limited to one game during the 2015 season after suffering an MCL injury. He told hip-hop artist Mike Seander in July 2019 (h/t Hunter Homistek of DKPittsburghSports.com) that while rehabbing from that injury, he was experiencing night sweats and had trouble sleeping.
He visited a doctor, who discovered tumors "surrounding" his heart.
"The doctor told me I had a week left," Conner said in the interview. "He said, 'You got about a week. If you [don't] get this treated, you [have] about a week at the rate it's growing.'"
Not only did Conner recover, but he also returned to the field for Pitt in 2016, running for 1,092 yards and 16 touchdowns.
ESPN honored him with the Disney Spirit Award during its year-end college football awards event.
Conner's football journey didn't end in college.
The Steelers selected him in the third round of the 2017 draft, and he enjoyed a breakout 2018 season while the team was engaged in a contract dispute with Le'Veon Bell. His 1,470 yards from scrimmage were 10th-most in the NFL.
