For the first five games this season, Kellen Moore served as the Dallas Cowboys’ backup quarterback to starter Dak Prescott.
That streak ended Sunday when Moore was made inactive for the game against the San Francisco 49ers.
Instead, undrafted rookie Cooper Rush assumed the backup role behind Prescott. The Cowboys won 40-10, and Rush got in the game with a little more than 6 minutes left. He completed a 2-yard pass to Ryan Switzer and also had two carries for 13 yards.
“It was just too good an opportunity to get Cooper Rush some snaps,” Cowboys owner Jerry Jones told a Dallas radio station on Tuesday.
