Joe Marler's jaw is smashed by the shoulder of Leicester second-row Calum Green. It's a high tackle, seemingly a red card offence.
But referee Wayne Barnes' deliberations with TMO Tom Foley at Harlequins' Twickenham Stoop overruled any such sanction, instead penalising Marler's team-mate Alex Dombrandt for pushing him into contact.
On 35 minutes, loosehead prop Marler took the ball into contact with Dombrandt behind him helping to send him on his way, leading to Barnes' consultation with the television match official.
