Facing off in Week 9, the Denver Broncos and Carolina Panthers played a competitive back-and-forth matchup during Sunday’s early window. With Bryce Young and the Panthers’ offense driving late in the third quarter, the fourth-year quarterback targeted tight end Tommy Tremble in the end zone on a play that was initially ruled incomplete.

Replays created confusion over whether Broncos head coach Sean Payton had challenged the ruling in time. Carolina ran another play, but officials said they had seen Denver’s challenge flag before the snap and went back to review the previous play. The ruling was changed to an interception by safety Devon Key, prompting a strong reaction across the NFL.

NFL World Explodes After Controversial Challenge in Broncos vs. Panthers Game

After a slow start, the Panthers’ offense got going in the second quarter and carried that momentum into the third. Carolina opened the second half with a six-play, 65-yard touchdown drive to take a 14-13 lead.

After forcing Denver into a three-and-out, Carolina then drove 92 yards in 12 plays and reached the Broncos’ 1-yard line.

A defensive pass interference penalty set the Panthers up at the 1, but Tremble could not secure Young’s target in the end zone. The play was initially ruled incomplete before replay changed the call to an interception by Key.

NFL reporter Ari Meirov shared a clip of the remarkable play, writing, “Ok. Wrap it up. This is the wildest interception of the season. Unbelievable.”

The interception itself was unusual, but so was the way the review unfolded. Carolina had already run its next play before officials announced that Denver’s challenge of the previous snap would be accepted. Officials determined that Payton’s challenge flag had been seen before the second-down snap, allowing them to go back and review the first-down play.

Yahoo’s Josh Norris reacted to the sequence, writing, “So the Refs let the challenge count? After the play was run?”

Panthers beat writer Sheena Quick provided more context surrounding the play.

“Broncos are contending that they threw the challenge flag before the 2nd & goal play from the 1 (which was fully executed) was snapped. I’ve never seen this before. A whole play was run but the refs reviewed the 1st & goal play from the 1 and conclude that Young’s pass was intercepted in the end zone.”

The turnover proved costly. Carolina was threatening to extend its 14-13 lead, but Denver instead took possession and drove 80 yards for a touchdown.

SiriusXM’s Geoff Schwartz summed up the swing: “Here comes the Broncos late game madness. They get a weird tipped pass interception in the end zone as the Panthers are trying to take an 8 pt lead.”

Denver eventually turned the takeaway into a touchdown, with Jonah Coleman scoring from nine yards out to put the Broncos ahead 19-14.

One Panthers fan expressed frustration over the sequence, posting on X, “1st and goal, ball at the 1, goofy [expletive] play, missed PI, gets the next play off, ref announces challenge flag was thrown before the snap, goofy [expletive] play gets more goofy and turns into a Bryce Young interception in the end zone, but I’m SURE THIS HAPPENS TO OTHER FANBASES.”

Panthers analyst Edgar Salmingo Jr. also criticized the outcome of the review.

“Football gods better make Sean Payton and the Broncos pay for the Panthers being screwed over on that replay.”

Denver ultimately held on for a 26-21 win despite Carolina’s fourth-quarter comeback attempt.

The loss dropped the Panthers, who rank 10th on PFN’s Offense Impact Metric, to 3-5, matching the Tampa Bay Buccaneers and New Orleans Saints in the win-loss column after Sunday’s early games, while the Atlanta Falcons fell to 3-6.

Tampa Bay still had its Sunday night game against the Chicago Bears remaining, leaving the NFC South standings unsettled heading into the night.
