In the Broncos’ 17-16 loss to the Seahawks on Monday Night Football in the season opener, Denver had the ball at the 1-yard line on two occasions and fumbled it away both times. Here’s a look at that second fumble that contributed to the upset loss.

The situation: Broncos down 17-13, 3:09 left in the third quarter, facing third-and-goal at the 1-yard line.

The formation: Denver came out in “shotgun doubles,” with KJ Hamler and Jerry Jeudy in opposite slots, Courtland Sutton on the left side and tight end Eric Tomlinson split out wide on the right side. Tomlinson then motioned to the line before the snap. Javonte Williams set up in the backfield to the right of Wilson.

The play call: Draw play to Williams, with the play designed to run right.

The result: A hit and forced fumble on Williams in the backfield by Seattle linebacker Uchenna Nwosu, with assistance from safety Josh Jones; recovered by cornerback Mike Jackson in the end zone for a Seahawks touchback.

The breakdown: Right guard Graham Glasgow, stepping in for an injured Quinn Meinerz (hamstring), got blasted on the play by Seattle defensive lineman Al Woods. The 330-pound veteran drove Glasgow back off the ball and right into Williams just after the tailback got the handoff at the 4-yard line. That collision stopped Williams’ momentum, then Nwosu — who beat Tomlinson at the line after the tight end whiffed on his block — punched the ball out as Jones also came in unblocked for the tackle. The loose ball careened off Williams’ leg and into the end zone, where Wilson and left guard Dalton Risner were too late to pounce on it.

The fallout: Williams’ cough-up was the Broncos’ second fumble at the one-yard line after Melvin Gordon fumbled there on fourth-and-1 on Denver’s prior possession. With those two blunders, Denver became the first team since the 1987 Chiefs to lose two fumbles at the opponent’s 1-yard line in the same game. The Broncos were unable to recover from those mistakes in the one-point loss when Brandon McManus missed a 64-yard field goal in the waning seconds.

Center Lloyd Cushenberry said the poor blocking on Williams’ run was a result of “miscommunication,” with Glasgow one of several who was confused up front for Denver. The latter dropped back as if in pass protection, which explains how he got blown off the line so thoroughly.

“(With) the crowd noise, we weren’t all five on the same page,” Cushenberry said. “We checked to another play but didn’t really all get (the call) and then didn’t convert. We have to clean that up for sure.”

Head coach Nathaniel Hackett added “that’s one I wish I could have back and just had a straight play call.”

“Russ is so good at seeing defenses so he wanted the opportunity to take advantage of a defense that he saw, and he did,” Hackett said. “He got up there and he checked (the play call), but as he starts audibling, (the crowd) gets louder. I think he thought everybody heard, but unfortunately, a couple guys didn’t.”
