Dallas Cowboys fans might want to look away.
The team's star cornerback, Trevon Diggs, picked off quarterback Dak Prescott twice during Tuesday's practice:

Those weren't Prescott's only turnovers on the day, however:

The concern is that Prescott was a turnover machine last season, throwing 15 interceptions in just 12 games while also losing a fumble.
