Nick Chubb injury: Surgeon claims NFL career could be over as disturbing image emerges

Orthopedic sports physician Dr. David Abbasi thinks Cleveland Browns running back Nick Chubb's season-ending injury might finish his career.

Abbasi added, "You can see he gets hit on his knee," examining the clip. "When his legs moved up, his knee popped back in.

The Browns' Week 2 "Monday Night Football." game against the Pittsburgh Steelers injured Chubb's knee.

In the second quarter, Chubb was instructed to sprint through the Steelers' defensive line. 

Safety Minkah Fitzpatrick dove at the runner's legs as he carried a Steelers defender.

Chubb's left foot was planted when Fitzpatrick's helmet hit his leg, bending its lower half.
