While the Atlanta Falcons gave the San Francisco 49ers their first loss of the season on Sunday, wide receiver Drake London did not appear too happy during the middle of it.

With 5:24 left in the third quarter and a 19-14 lead over San Francisco, London was seen yelling at one of the referees during the game.

It’s unknown what exactly London said, but speculation on social media suggests that he said, “You a b—h!”

The video started off with London talking to a member of the Falcons organization on the sideline, then walking down and turning his head back at the last second to voice his frustration at the official.

Before the heated exchange between the former standout wide receiver from USC and the official, London was caught in the middle of a scary play with 49ers safety Malik Mustapha, when the two collided head-on and had a helmet-to-helmet play, resulting in London being evaluated for a concussion.

This isn’t the first time London has gone viral for his words.

In September, London got into a heated exchange that he claims got “personal” during a blowout loss to the Panthers.

Luckily for London, he was cleared to remain in the rest of the game after the hit and played a key part in helping his team get a 29-20 victory.

On the first play of the first quarter, London gave Atlanta a big time play when he caught a 21-yard touchdown reception to extend the Falcons’ lead to 26.

Atlanta’s defense held on in the fourth, forcing two turnovers. The first was when Brock Purdy threw an interception to Kendal Daniels at the 2:42 mark of the quarter.

Their next turnover came when safety Jesse Bates punched the ball out of George Kittle’s arm, setting up an Atlanta recovery.

The Falcons ran out the clock to end the game.

London finished as the team’s leading receiver, hauling in seven receptions for 66 yards and one touchdown.
