The initial diagnosis was a dislocated left knee and torn ligaments. The MRI also revealed that he had torn his MCL, PCL, and LCL, as well as cartilage damage.
Chubb is one of the best running backs in the NFL and his injury is a major blow to the Browns. He was coming off a season in which he rushed for over 1,200 yards and 10 touchdowns.
The Browns still have a lot of talent on their roster, but Chubb's injury is a major blow. They will need to find a way to replace his production if they want to be competitive in the AFC North.
