According to Dak Prescott, he will undergo surgery on his right thumb on Monday.
He sustained an injury during Sunday night's 19-3 loss to the Tampa Bay Buccaneers in the season opener.
During a pass attempt in the fourth quarter, Prescott collided with outside linebacker Shaq Barrett's hand and sustained an injury.
Prescott will see the Cowboys' hand specialist on Monday, but many sources say he'll get a pin and plate to stabilise the joint.
Prescott's 134 yards were the second-fewest he's recorded in a career-starting game.
On November 30, 2017, he completed 11 of 22 passes for 102 yards while playing Washington.
After starting 69 straight games from 2016 to 2020, Prescott has missed 12 the last two seasons and could miss seven this season.
Nov. 6 is the Cowboys' bye week, and Nov. 13 is their away game against the Green Bay Packers.
