Revealed - why Arsenal defender Gabriel had red card overturned in chaotic Leeds United clash
and live on Freeview channel 276
With the Whites searching for a dramatic equaliser and dominating the second half, Gabriel tangled with Patrick Bamford in the visitors' penalty area and appeared to kick out at the striker. Kavanagh took advice from his assistant as Bamford appealed to the officials and the on-field decision was a penalty and a red card for Gabriel.
But before Bamford could try again from the spot, after missing an earlier penalty, Kavanagh was summoned to his pitchside monitor to view a possible foul by the Leeds striker. The referee decided that Bamford's barge on the Brazilian was indeed worthy of a free-kick, so overturned his original decision, but he also cancelled his red card and instead showed Gabriel a yellow.
The YEP understands that Gabriel's actions were deemed as unsporting behavior and not serious foul play. Leeds were left to rue their own performance in the Arsenal penalty area, missing a glut of second half chances including that spot-kick that Bamford drilled wide of Aaron Ramsdale's left-hand post.
Leeds boss Jesse Marsch revealed after the game that there was briefly a possibility that the game could go ahead without VAR due to a power surge that knocked out the Premier League's systems at Elland Road. It led to a delay of around 30 minutes, before the game resumed with VAR and Hawkeye rebooted and in operation.
