Flores helped get Andy Carroll sent off during the Hammers' win at Upton Park.
Karren told The Sun in her weekly diary: "Andy Carroll is red-carded for what amounts to accidentally disturbing the ponytail of an opponent.
"Swansea's Chico Flores clutches his face and rolls around bodypopping on the floor like he's been shot. It's one of the worst cases of bad sportsmanship I have seen in 20 years.
"Swansea can pick Chico Flores who pretended that he had suffered what appeared to be at least brain damage when his ponytail got 'air' brushed by Andy's arm.
"I had brain surgery in 2006 and even then I didn't roll around four times."
