Tyler Reddick raced Sunday with his championship hopes on the line at the same time his infant son has been diagnosed with a tumor in his chest that is affecting his heart. Rookie Reddick, the second of Tyler and Alexa Reddick's two boys, was born in May and Alexa revealed last week that he has been dealing with serious health complications. The couple provided an update ahead of Sunday's race at The Roval at Charlotte Motor Speedway, where Reddick was starting from the pole and needs a victory to remain in contention for the Cup Series title.
