Chelsea fans were left fuming after referee Paul Tierney - and VAR officials - decided not to send Tottenham's Matt Doherty off for a studs-up challenge on Malang Sarr.
20 minutes of the first half had been played when the Spurs and Ireland defender went in late and appeared to catch Sarr on the shin with his studs.
The 23-year-old looked to be writhing in agony as medical staff rushed on to the Stamford Bridge pitch but got back to his feet moments later after receiving attention.
