FRISCO (CBSDFW.COM) – The Dallas Cowboys reportedly be without starting quarterback Andy Dalton again this Sunday.

Sources say the team will place Dalton, who suffered a concussion on October 25 after an illegal hit during the game against the Washington Football Team, on the reserve/COVID-19 list Tuesday.

Dalton was out last week when the Cowboys fell hard to Philadelphia during rookie quarterback Ben DiNucci’s first start and being put on reserve means Dalton will miss this Sunday’s game against the Pittsburgh Steelers.
