While Alvaro Carreras and Endrick saw red in injury-time for their protesting, ref Alejandro Quintero Gonzalez showed a first red card to Fran on 64 minutes.
The fullback was dismissed for two bookings, the first came on 62 minutes when he made a 'technical foul' to prevent a Celta breakaway.
However, the second yellow card - just two minutes later - infuriated his coach as Garcia was late on Williot Swedberg with his tackle and then struck the Swede in the face with a flailing arm.
Quintero had no option but to show the defender a second yellow card and then the red.
In the aftermath, Xabi was heard shouting, "Fran, don't mess with me!", before Quintero showed the player the red card.
