Dallas Cowboys owner Jerry Jones believes the team should “adjust expectations” after star quarterback Dak Prescott was lost for the season.

The Prescott injury has Jones changing his forecast for the Cowboys' season despite having veteran gunslinger Andy Dalton stepping in for Dak.

“We should adjust expectations. (It's) different than optimism. But we should adjust our expectations. Dak is a very incremental part of the potential success to this football team,” Jerry Jones said Friday on the K&C Masterpiece on 105.3 The Fan.

“On the other hand, if we don't reach where we want to go … and the ultimate success is to win the championship … it will not be because of Andy Dalton. It will not be because of our play at quarterback. He's capable of stepping in and playing at that level.”

Dak Prescott was putting up MVP-type numbers for the Cowboys before he suffered that gruesome ankle injury in Week 5 against the New York Giants. The 27-year-old threw for 1,856 yards and nine touchdowns while completing 68.0 percent of his passes.

The Cowboys are 2-3 on the season and atop the NFC East standings. They'll host the Arizona Cardinals in Week 6 in the first game without Prescott.

Dallas wasn't going to win the Super Bowl this season even if Prescott didn't get hurt since the team has arguably the worst defense in the NFL. With that being said, it's going to be interesting to see how far Dalton can take the Cowboys now that Dak is done for the rest of the 2020 campaign.
