Nick Chubb has busted through barriers, pushing his body past the pain of two grueling rehabs from injuries. Chubb endured a painful knee injury two years ago against the Pittsburgh Steelers, a torn medial collateral ligament and sustained damage to his anterior cruciate ligament. Just when he was gaining traction again a year ago, he broke his foot against the Kansas City Chiefs. Now, the 29-year-old former Georgia star is regaining his footing with the Texans in a pivotal role.
