Cleveland Browns running back Nick Chubb (leg) was carted to the locker room in the second quarter of Monday's Week 2 game against the Pittsburgh Steelers.
Chubb suffered what appears to be a serious leg injury after a collision with a Steelers defender. The star running back was having an electric night prior to the injury.
Chubb was carrying Cleveland's offense by himself, rushing 10 times for 64 yards prior to his injury.
