Inside the Cowboys locker room at MetLife Stadium Sunday night, Jerry Jones said rookie quarterback Dak Prescott's ineffectiveness would not be a factor in replacing him with Tony Romo. It would take Prescott not being available for Romo to regain the starting job.

Prescott had his worst game in Sunday night's 10-7 loss to the New York Giants. In his last three outings, Prescott has been held under 200 yards passing while totaling 3 passing touchdowns, a rushing touchdown and 2 interceptions.

Head coach Jason Garrett made it clear Monday afternoon that the team is sticking with Prescott.

However, when Jones was asked again Tuesday morning what would it take to go back to Romo, Prescott's availability was not mentioned.

"I don't have a definition for it, but you'll know it when you see it," the Cowboys owner and general manager said on 105.3 The Fan's Shan and RJ show [KRLD-FM]. "It's kind of like the definition I heard one time of another issue -- trying to define a negative topic -- and they said: 'I don't know how to say it, but it's just something that when you see it, you know it's there.'

"We'll see it."

The quote was a callback to Supreme Court Justice Potter Stweart's definition of obscenity in Jacobellis v. Ohio: "I know it when I see it."

Jones said he is not tired of hearing the Dak/Romo questions. He says the franchise is fortunate to have their depth at quarterback.

But is there a scenario Jones envisions that would allow Romo to get back under center?

"I really don't want to get into the scenario, it goes too far in talking about what we don't want to talk about," Jones said. "Given the need for [Romo], we want him ready on the spur of the moment to be a part of any effort we make -- to be trite -- to win the ball game.

"It would be when we all probably thought it was time for him to come in and play. I don't want to give you those circumstances because I don't like either one of the discussions."
