Browns RB Chubb out with concussion after practice tackle

Cleveland Browns Pro Bowl running back Nick Chubb has been placed in concussion protocol after he sustained a head injury while being tackled during the team’s first fully padded practice. Chubb, who finished second in the NFL last season with 1,494 yards, was taken down during Monday’s workout with a high tackle by second-year linebacker Mack Wilson. The third-year back will sit out Tuesday’s workout and per league rules Chubb will have to pass several neurological tests before he’ll be permitted to return to the field.
