ORCHARD PARK, N.Y. — The Buffalo Bills filled their need for a third-string quarterback by signing Ben DiNucci, the player’s agency JL Sports announced on social media Monday.

The Bills have not yet announced the signing in part because they’ll have to make a corresponding move to free up a roster spot.

Earlier in the day, coach Sean McDermott said the team was considering adding a QB to replace Shane Buechele, who is out indefinitely with a neck injury.

McDermott did not reveal the nature of the injury in saying Buechele played through it after being hurt in Buffalo’s preseason-opening 33-6 loss to Chicago on Saturday. Adding a third QB was imperative because the Bills are limiting starter Josh Allen and backup Mitch Trubisky’s preseason playing time to avoid the risk of injuries.

Buechele finished the game after entering midway through the third quarter and went 6 of 10 for 53 yards, with an interception which linebacker Micah Baskerville returned 53 yards for a touchdown. Buechele was sacked six times and also had three carries for 22 yards.

The 27-year-old DiNucci was selected by Dallas in the seventh round of the 2020 draft after splitting his college career at Pittsburgh and James Madison. He previously starred at Pine-Richland High School. He went 23 of 43 for 219 yards in three NFL games — including one start, a loss — in his rookie year for the Cowboys.

DiNucci was released by Dallas before the start of the 2022 season, and spent last year with the Denver Broncos, before being released in May.
