WWE posted an interview with referee Charles Robinson, who revealed that he tore his plantar fascia (ligament in the heel of the foot) while refereeing the John Cena vs. AJ Styles match at the Royal Rumble.
WWE.COM: Were there any surprises during the match that the WWE Universe would be curious to hear about?
ROBINSON: I got hurt! I tore my plantar fasciitis like seven minutes into the match. So I’m limping around, trying to do the match — which was incredible — but what I was gonna do? Throw up the big “X” for myself?!
