The Tony Romo whispers, swirling for weeks now, grew to a dull roar by the third quarter. 

Then came a reminder as to why there's any debate in the first place.

Dak Prescott, the Dallas Cowboys' rookie quarterback, reconciled what had been his worst performance to date by leading a pair of championship-caliber drives to fend off the first-place-minded Philadelphia Eagles in a 29-23 overtime victory Sunday night at AT&T Stadium.

Prescott completed five of his 13 attempts in the first half, including an interception on second-and-goal from the Eagles 7-yard line. The third quarter wasn't much better, as rookie running mate Ezekiel Elliott was held in check and the Eagles opened a 10-point lead to start the fourth. For the first time, the Dallas offense lacked answers.

But with 6:26 to play, Prescott and the Cowboys set off from their own 10-yard line and something clicked. Ninety yards later, Dez Bryant, back from a five-week injury stint, caught a Prescott fade pass placed perfectly between two defenders for a game-tying 22-yard touchdown that would force overtime.

In the extra frame, Prescott completed all five of his passes and converted a crucial fourth-and-1 with his legs on an 11-play drive that ended when he found tight end Jason Witten wide open for the winning 5-yard score. It was Witten's first touchdown catch of the season.

Prescott's final stat line wasn't pretty. The record will show he completed 48.7

percent of his passes. But the poise and precision eventually shone through, and he added 38 yards and a touchdown on the ground. Jerry Jones has already named Prescott the starter for next Sunday's matchup with the Browns.

Dallas, after all, is riding a six-game win streak and sits firmly atop the NFC East.

With a loss, the Cowboys would have ceded the top spot to the Eagles, who instead fall to 4-3. Now, if Minnesota loses Monday night, they'll boast the best record in the entire NFC. Even with Romo's return to practice, it seems Dallas will stick to what has got it this far.

Elliott, entering as the NFL's leading rusher, failed to crack 100 yards on the ground for the first time since Week 2, but was the Cowboys' third-leading receiver with 52 yards on four catches. He had a 63-yard run negated on the Cowboys' final drive by a Travis Frederick holding penalty.

Bryant led the team with 113 yards receiving and a touchdown in his return.
