Dak Prescott's game-winning touchdown pass may have been costly for the Dallas Cowboys, though the star quarterback insisted "I'll be fine" after hurting his calf.

Rolling to his right, Prescott leapt to complete a 35-yard touchdown pass to CeeDee Lamb that gave Dallas a 35-29 overtime win at the New England Patriots on Sunday, but Prescott said he came down wrong on the play. 

Prescott walked into his post-game news conference wearing a protective boot and the team said he suffered a right calf strain on the final play. 

"It just came down funny and that's what it was," Prescott told reporters. "It's something we'll get checked out and I'll be fine." 

Prescott will have an MRI on Monday, but the good news for the Cowboys is they are entering their bye week and will not play again until an October 31 trip to face the Minnesota Vikings. 

That will provide valuable recovery time for Prescott, who saw his 2020 season end in Week 5 with a fracture and dislocation of his right ankle. 

There are no indications this will be a serious setback for Prescott, who did not play in the preseason this year, but the Cowboys can ill afford to lose him for any significant period. 

"Life keeps throwing punches and I'll keep throwing them back," Prescott said. "It doesn't hurt as bad when you score and win the game."

Prescott completed 36 of 51 passes for 445 yards with three touchdowns and an interception as the Cowboys beat the Patriots for the first time since December 1996 after six consecutive losses in the interim.

His yardage total is the most allowed by the Patriots in head coach Bill Belichick's 22 seasons with New England, topping a 438-yard game by Peyton Manning in November 2014. 

"I can't say enough about Dak Prescott, the way he was distributing the ball, his poise and confidence in the pocket," said Cowboys head coach Mike McCarthy. 

"He never wavered. His process was the same throughout. He's on top of his game right now."
