Zach Ertz nearly saw his go-ahead touchdown catch that lifted the Philadelphia Eagles to the franchise’s first Super Bowl victory overturned by the NFL’s confusing catch rule.

“If they had overturned that, I don’t know what would have happened to the city of Philadelphia,” a smiling Ertz said on the stage at U.S. Bank Stadium in Minneapolis after the Eagles’ 41-33 victory.

Ertz caught the ball and took three steps before diving into the end zone. After the ball crossed the goal line, the tight end lost control.

It was called an 11-yard touchdown on the field for a 38-33 lead with 2:21 to play. But the play looked similar to the TD scored by Pittsburgh Steelers tight end Jesse James that was overturned in a regular-season loss to New England, so there was no certainty about the result of the review until Ertz’s TD was upheld.

A catch controversy caused confusion earlier on the NFL’s biggest stage at Super Bowl LII, as well.

Eagles rookie running back Corey Clement hauled in a 22-yard touchdown pass from Nick Foles to put Philadelphia up, 29-19, on the Patriots with 7:48 remaining in the third quarter. Clement got two feet in bounds before his toe on his third step touched the white line at the back of the end zone.

The play was called a touchdown on the field, and that appeared to be the correct call. But when it went to review, NBC announcers Al Michaels and Cris Collinsworth both felt strongly that Clement’s catch would be overturned incomplete.

Plenty of media covering the game agreed that Clement’s slight bobble of the ball meant he had not established possession until his second step and therefore had gotten only one foot in bounds before touching the white line.

This was based on the NFL’s overturning of several similar calls this season based on a backward catch rule that league commissioner Roger Goodell is making a priority to correct with the competition committee this offseason.

But Al Riveron, the NFL’s head of officiating who was in Minneapolis to review all replays as he had all season from the league headquarters in New York, upheld the call of touchdown on the field by referee Gene Steratore’s crew.
