Jason Kelce heads down the tunnel during Eagles' game against the Bills to use the BATHROOM... before returning to help Jalen Hurts score winning TD in overtime and seal Philadelphia's place in the playoffs

When Jason Kelce headed down the tunnel after giving away two late penalties against the Bills, Eagles fans were left fearing the worst with overtime looming.

In the end they needn't have worried, however, as the veteran center soon returned to the field and went on to help Philadelphia seal their place in the NFL playoffs.

Kelce made a crucial block on a Bills defender which allowed Jalen Hurts to run through to the end zone and win the game for the Eagles, who are the first team to make it into this season's playoffs.

And according to NFL reporter James Palmer, his short trip down the tunnel beforehand was simply to use the bathroom.

By relieving himself ahead of overtime and returning for the coin toss, Kelce showed his experience after two rare lapses in concentration saw him penalized for false starts.

However, after using the bathroom Kelce rediscovered his best form and proved the unsung hero as Hurts scored the game-winning touchdown. 

Hurts scored the winning touchdown on a quarterback draw with 2:37 left in overtime to help the Eagles win 37-34 on a cold, rainy Sunday. 

Philadelphia's Jake Elliott tied the game with a 59-yard field goal with 20 seconds remaining. After the Bills went ahead with a field goal on the first possession of OT, Hurts ran virtually untouched for the 12-yard score that made the Eagles the only 10-1 team in the NFL.

Hurts threw for three touchdowns and ran for two more, and he outdueled Buffalo's Josh Allen while rallying the Eagles from a 17-7 halftime deficit for the second straight game.

Hurts walked off the field with his arms extended in celebration as fans roared. He hit DeVonta Smith for 17- and 11-yard receptions in OT, and D´Andre Swift had a 16-yard run to help set up Hurts´ walk-off TD.

Allen threw for 339 yards and two touchdowns and ran for two scores for the Bills (6-5), who are in danger of missing the playoffs after winning the AFC East the past three years. But he was intercepted in the fourth quarter by James Bradbury, setting up Hurts' 29-yard TD pass to Olamide Zaccheaus for a 28-24 Philly lead.

Allen used a 15-yard scramble and a 15-yard roughing the passer penalty on the first drive of OT to put the Bills in position for the win. Tyler Bass - who had missed two field goals - nailed the go-ahead kick from 40 yards with 5:52 left in OT.
