When Dallas Cowboys quarterback Dak Prescott was fully cleared for practice last week, it was understood he was a full go for for the Sept. 9 season opener against the Tampa Bay Buccaneers.

It was the news that the team had always expected following the right shoulder strain he sustained during a July 28 practice, but for those that didn’t consider that to provide enough certainty, team owner Jerry Jones made it official before Sunday’s preseason finale against the Jacksonville Jaguars.

Jones said Prescott was “good to go” while on the Cowboys pre-game show on 105.3 The Fan.

“He turned it loose and was none the worse for it,” Jones said of Prescott’s work in practice. “The MRIs are showing all systems go. He’s throwing with velocity [and] emphasis, throwing on the run.’’

Prescott did not play in the team’s first three preseason games and he was among the 30 Cowboys held out of Sunday’sgame.

When Prescott takes the field against the Buccaneers, it will be his first live action since suffering a fractured right ankle last October against the New York Giants.

The Cowboys had hoped that Prescott would be able to log time with the offense during the preseason, but that changed when with the shoulder injury.

McCarthy said the offense has already taken a positive step forward with Prescott in practice over the last week. He said they will focus on getting Prescott more competitive reps and throws leading up to the season opener, now less than two weeks away.
