‘In addition to Trubisky’s battle against his former team, Saturday’s matchup will feature the preseason debuts of left tackle Dion Dawkins and running back Zack Moss. After making significant progress in his return from COVID-19, Dawkins will get the start at left tackle. His performance against the Bears could play in a role in whether or not the Bills play Josh Allen in the team’s preseason finale against the Packers. Moss, one of the Bills’ lead backs, will return from a hamstring injury that kept him out of the team’s first preseason matchup against the Lions.’
