Swansea manager Michael Laudrup has urged Chico Flores to improve his behaviour against Fulham or risk a suspension.
The Spanish defender has been widely criticised for over-reacting to challenges this season, particularly their most recent home games against West Ham and Stoke.
Hammers boss Sam Allardyce laughed at Flores rolling around on the turf before the pair became embroiled in a touchline row.
The Spaniard was struck in the throat by Stoke's Steven Nzonzi, but he fell to the ground clutching his face and was booked for his actions, prompting Potters striker Jon Walters to call for Flores to be banned.
That booking was Flores' fourth of the season and a fifth against Fulham on Saturday would see him suspended.
"He has to avoid it," said Laudrup of his theatrics. "I'm of an opinion where if there is too much spotlight on a player for certain things, right or wrong, referees are human and, if a player is said to dive a lot, then when I take charge of that team I have it in my mind.
"We have seen cases, and you can say it may be fair or unfair, with Gareth Bale and Luis Suarez.
"We have to avoid it with Chico because if someone really does hit him, instead of it being exaggerated, then maybe the other player gets punished.
"We know how the rules are here with the cards and he knows he will be suspended after the next one and of course it's important to try to avoid that.
"Obviously the position he plays means that he will get more cards over a season than others but we have to avoid bookings for this."
Laudrup also believes that Nzonzi could have been sent off had it not been for the actions of Flores in a game that finished 3-3 when Charlie Adam converted a controversial last-minute penalty.
"We can agree that Chico was definitely not dead and he played on, but if we have to take the letter of the law, he (Nzonzi) actually hit him and it says in the law if he hits him it's a red card," Laudrup added.
"But there I think the referee did okay. Even If the law says that, I don't think Nzonzi should have had a red card. But then you can argue did he exaggerate? Yes, Chico did, but why give him a yellow?
"Maybe in that situation if I was the referee I would just take the two of them and say 'hey, I saw that Nzonzi. Next time, you are off and Chico, don't play around and play dead as you are not'.
"But to tell the truth it should have been a red card and a yellow card."
