"This is the opportunity of a lifetime," the rookie said Thursday, per Clarence Hill Jr. of the Star-Telegram. "... This is everyone's childhood dream. Getting a chance to be starting quarterback of the Dallas Cowboys. What more do you want?"
The 2020 seventh-round pick began the year third on the depth chart, but the Cowboys need help at the position after Dak Prescott suffered a season-ending ankle injury in Week 5 and Dalton suffered a concussion in Week 7.
DiNucci saw his first extended action last Sunday against the Washington Football Team, going 2-of-3 for 39 passing yards in two drives of a 25-3 loss. He also fumbled twice, although his team recovered both.
He will seemingly get a chance to make it up in Week 8 with a win giving the team at least a share of first place in the NFC East.
It represents a quick rise in responsibility for a player who spent last season playing at FCS James Madison. He finished last season with 3,441 passing yards, 569 rushing yards and 36 total touchdowns.
With a lot of weapons around him like Ezekiel Elliott, Amari Cooper and CeeDee Lamb, DiNucci will hope to produce some big numbers now in the NFL.
