Josh Allen will become the second rookie quarterback from the class of 2018 to start when the Buffalo Bills play the Los Angeles Chargers on Sunday, league and team sources told ESPN's Chris Mortensen on Wednesday.
Bills coach Sean McDermott is expected to make it official later Wednesday.
The decision by McDermott and his staff came after a full evaluation of Sunday's 47-3 road loss to the Baltimore Ravens, sources said.
Allen's athleticism and ability to make intermediate throws were plus-factors and the staff believes it will enable the run game to enjoy more success, sources told ESPN.
While the offensive line was dominated by the Ravens, sources said the evaluation of Sunday's game also assigned three sacks to starting quarterback Nathan Peterman, who moves into the backup role behind Allen.
