The Bears on Sunday placed right tackle Elijah Wilkinson and linebacker Caleb Johnson on the reserve/COVID-19 list.
They also flexed second-year pro Arlington Hambright from the practice squad to the active roster. Selected by the Bears in the seventh round of the 2020 draft, Hambright appeared in nine games with one start last year as a rookie.
The Bears now have four players on the COVID-19 list, with Wilkinson and Johnson joining tight end Jimmy Graham and outside linebacker Robert Quinn.
