The Cleveland Browns are keeping a close watch on running back Nick Chubb, who is still recovering from a serious knee injury. He may not be cleared to play and is expected to start the season on the physically unable to perform list.

This status would mean he misses at least the first four games and does not impact the team's 53-man roster until he is activated. The Browns are currently relying on other running backs like Jerome Ford and Pierre Strong for the early part of the season.
