quarterback is unlikely to play in Sunday's game against the Philadelphia Eagles.
Per ESPN's Adam Schefter, the Cowboys have officially listed Dalton as doubtful with a concussion.
Dalton suffered the concussion during the Cowboys' Week 7 loss to the Washington Football Team, which he was only starting because Dak Prescott was sidelined with an ankle fracture. That left Ben DiNucci, who was a seventh-round draft pick out of James Madison, under center.
Dallas had legitimate championship aspirations coming into the season and surely didn't envision the 23-year-old receiving meaningful snaps in 2020.
