Kalis was promoted to the active roster Saturday, Nate Ulrich of the Akron Beacon Journal reports.
Kalis will help provide some depth on the offensive line Sunday as Austin Corbett (foot) will not play and J.C. Tretter (ankle) is listed as questionable. In a corresponding move, the Browns waived wide receiver Da'Mari Scott.
Kalis was waived by the Colts due to injury in 2017 and was picked up by the Redskins before their last regular-season game. Kalis is still fighting for a spot on Washington's final roster heading into the 2018 season.
