The Los Angeles Chargers came into their game against London today fresh off three straight wins, with last week seeing them dismantle the Cleveland Browns in a 38-14 drubbing that was utter domination from start to finish.
The Chargers were expected to run away with it against the Tennessee Titans at Wembley, with many - us included - believing the game wouldn't be close at all and a blowout was the only outcome on the cards.
Thankfully for everyone inside the stadium, the Titans fought hard and got themselves back into in the second half. And that seemingly took the Chargers by surprise, which led to some anger on the sidelines, most notably from Keenan Allen.
Allen may have finished Sunday's early game with five receptions for 72 yards, a very respectable stat line, but he still wasn't happy on one play in particular.
With the scoreline reading 17-13 in his team's favour, with 10 minutes left in the fourth quarter, Allen ran a beautiful route on the goal line that saw him break free from his defender. Someone who didn't see it though was Philip Rivers.
Instead of hitting the Chargers number one wideout, Rivers instead tried to feed the ball to Mike Williams - who had scored earlier in the game.
But Williams couldn't add to his tally as he dropped the pass, and Allen went ballistic.
The wide receiver was hopping mad into the endzone before unleashing his anger with a kick to the pylon and then followed it up by storming onto the sideline and shouting at no one and everyone as receivers coach Rob Moore tried to cool him down.
Take a look at the moment here...
Thankfully for Allen, and all the other remaining pylons and equipment on the Wembley field, the Chargers did run out eventual winners - taking a 20-19 victory when the Titans went for two and failed after a last-minute TD.
But imagine if Odell Beckham did this. It would be front page news. How long will we hear about Allen's outburst? It's probably already forgotten.
