Eagles WATCH: DeVonta Smith's Hilarious Reaction to Justin Jefferson Fumble

Philadelphia Eagles receiver DeVonta Smith had a funny reaction to the fumble by Minnesota Vikings receiver Justin Jefferson during Thursday Night Football in Week 2.

As per usual, Minnesota Vikings receiver Justin Jefferson was incredibly productive during the team's Week 2 matchup with the Philadelphia Eagles. However, a mistake that Jefferson made arguably was his defining play in what ended up being the second consecutive loss by the Vikings to open the season, as Minnesota fell 34-28 to the Eagles in Philly last Thursday.

While Jefferson hauled in 11 passes for 159 yards in Week 2, his second-quarter fumble through the back of the end zone that ended up being a touchback for the Eagles proved to be a turning point in the game. Rather than at least kicking a field goal -- if not eventually punching it in for a touchdown -- the Vikings had to settle with going into halftime down 13-7.

Eagles wideout DeVonta Smith was mic'd up for the game by NFL Films, and joked that after the change of possession, Jefferson's ill-fated reach for the pylon would become an example of how not to act so close to scoring a touchdown.

Of course, the fumble through the back of the end zone resulting in a change of possession and a touchback is one of the most controversial rules in the NFL. Some believe that the opposing team should be forced to take the ball on their own one-yard line after "recovering" a fumble through the back of the end zone. Others believe there shouldn't be a change of possession at all, and that Jefferson and the Vikings simply should have retained the ball at the Eagles' one-yard line.

In any event, receivers are aware of the current rule on the books, and Jefferson probably should have just lived to see another down. Instead, Smith -- who had four catches for 131 yards and a touchdown himself -- and the Eagles ended up moving to 2-0, at least in part thanks to Jefferson's miscue.
