Lamar Jackson and the Ravens made things interesting, but Buffalo's defense held on to give the Bills a victory in Sunday's AFC divisional round matchup.

A strange situation occurred during the Buffalo Bills' big wild-card win over the Denver Broncos. After Josh Allen went to the bench, head referee Bill Vinovich came over and talked privately with him.

Referee Bill Vinovich was spotted having a conversation with Bills quarterback Josh Allen following a controversial non-call.

When the NFL announced its officiating assignments for the weekend’s wild-card round games, Bills fans were notably upset to see that Bill Vinovich’s crew was tabbed to work Buffalo’s game against the Broncos.

Oddsmakers have set them as just 1.5-point underdogs to win the AFC title game, and Allen and company did beat the Chiefs in the regular season. Allen's playoff record as an underdog (1-3, 0-3 on the road) is concerning, but the Bills did technically upset the Ravens on Sunday.

Officiating a game in the NFL is a pretty difficult job, as the players are so big and fast that it's hard to truly catch everything that's happening.

Throughout the season, Surtain was known for his ability to blanket opposing No. 1 receivers and completely erase them from the game. In this wild-card game, he'll be remembered for getting away with an egregious holding penalty on Bills' tight end Dalton Kincaid.

Head referee Bill Vinovich came over to Allen while he was sitting on the bench afterwards and spoke to him. Many believed Vinovich was explaining to Allen why a penalty wasn't called, which is a very odd occurrence. Referees do not wander over to the bench to chat to players very often, especially not star quarterbacks while they sit on the bench.

Josh Allen and the Bills' run game got whatever they wanted against the Broncos' defense on Sunday, as Buffalo advanced to face Baltimore in next week's divisional round.
