Genge addressed the video and why he may not have been clapping: "Don't know why I'm not clapping in that tunnel must be deep in thought, utmost respect for the Welsh… as for keyboard warriors sending death threats etc", accompanied by a video of MMA champion Khabib Nurmagomedov saying 'send location'.
At the final whistle, the Leicester prop appeared annoyed by Welsh halfback Gareth Davies, who had the final say of the game when he kicked the ball into touch.
Given that the tunnel was a few moments later, Genge might not have been in the mood for the traditional clap off. Either way, a pretty innocuous incident by any measure.
Genge's death threats were just the latest unsavoury aftertaste following the weekend's rugby. England skipper Owen Farrell received a tirade of abuse, while BBC presenter Sonja McLaughlan was left in tears following the match after her post-match interviews were derided online by a minority of angry fans.
"Toxic, embarrassing, disgraceful, appalling. Just some of the feedback I've had," McLaughlan wrote on Twitter. "Thanks for using @ sign so it's all hit home. Now imagine getting inundated with abuse for doing your job. In my car crying. Hope you're happy."
It lead to the BBC, the Six Nations and England Rugby to condemn the abuse she suffered. For a sport that prides itself on respect, this weekend feels like a low watermark.
