The difference between a touchdown and a touchback can be dangerously close, which Vikings Receiver Justin Jefferson learned the hard way during Thursday night’s game against the Eagles in Philadelphia. 

Jefferson, 24, looked as though he was about to put the Vikings ahead at the end of the first half when Kirk Cousins hit Jefferson for a 30-yard pass.

But as Jefferson ran toward the goal line and was tackled, he lost control of the ball and fumbled it out of bounds into the end zone.

The officials huddled to decide on the call and ultimately, after it was reviewed, they ruled that it was a touchback because the ball had been fumbled inside the pylon and thus out of the end zone, ending a 74-yard drive in disastrous fashion with just 33 seconds left on the clock in the half. 

To make matters worse, after the Eagles got the ball back, they converted on a 61-yard field goal before halftime to pad their lead to 13-7. 

The fumble rule has long been a bit of a controversial one, and some people on social were not happy when it reared its ugly head on Thursday. 

Punter-turned-sports-media-darling Pat McAfee chimed in on X, formerly known as Twitter, after it happened.

“Man… touchbacks are the focking worst,” he wrote. 

“Always think this is a dumb rule — why should the defense get the ball here if they rule a fumble over the pylon? If you fumble the ball out of bounds anywhere on the field, the defense doesn’t get it,” wrote CBS47/FOX30 (Jacksonville) sports director Brent Martineau. 

The Jets were victimized by the rule in 2017 during a heartbreaking loss to the rival Patriots.

Tight end Austin Seferian-Jenkins appeared to score a touchdown before the officials overturned the call upon video review, calling it a touchback. 

The call cost the Jets the game, which they lost 24-17. 

Jefferson had five catches for 57 yards in the first half of Thursday’s game for Minnesota and had reached 5,000-plus receiving yards — the fastest in NFL history to do so — on the drive that he eventually fumbled on.
