Chubb, who remains on the reserve/COVID-19 list, wasn't present for Friday's practice, Mary Kay Cabot of The Cleveland Plain Dealer reports.
The same applies to Demetric Felton, with Cabot noting that the deadline for the Browns to activate either back is Saturday afternoon. If Chubb isn't cleared in advance of Sunday's game against the Patriots, D'Ernest Johnson would be in line to start at running back for the team in Week 10.
