Dallas Cowboys' Mike McCarthy confirms Dak Prescott strained calf, optimistic he'll play at Minnesota on Oct. 31

Dallas Cowboys coach Mike McCarthy on Monday said an MRI confirmed Dak Prescott strained his right calf, but he remains optimistic about the quarterback playing at Minnesota on Oct. 31 after the team's bye week.

Prescott suffered the injury on the game-winning touchdown pass to CeeDee Lamb that gave Dallas a 35-29 overtime victory over the New England Patriots on Sunday. He had to be helped off the field and wore a walking boot while meeting with reporters after the game.

"I've got a lot of confidence in myself and the medical team, and as I said, I feel good,'' Prescott said Sunday. "This (the boot) is a precaution. Didn't hurt as bad, obviously, when you score and win the game.''

The injury is in the same lower leg that needed two surgeries after Prescott's season-ending compound fracture of his right ankle in Week 5 last year.
