Carolina Panthers rookie running back Jonathon Brooks has been downgraded to out and will not be activated for the Week 8 game against the Denver Broncos due to a knee injury. Despite limited practice over the past two weeks, the Panthers are exercising caution with Brooks as he continues to recover from knee surgery. Chuba Hubbard is expected to lead the backfield in Brooks' absence, especially with quarterback Bryce Young returning to the lineup.
