Coventry City manager Micky Adams has told leading scorer Gary McSheffrey to eradicate the theatricals after the striker was handed a costly caution for diving last weekend.
The striker's tenth yellow card of the season was issued when he went down in the penalty area, claiming a penalty, during the 3-1 defeat to Plymouth Argyle and is facing a two-match ban.
Adams estimates that half of that total is due to the 23-year-old's propensity to go to ground at the slightest contact and he has spoken to the player about his conduct.
"I have had a quiet word with Gary," said Adams, who will also be without Ady Williams for Saturday's home game with Burnley after the defender was cautioned for dissent, his fifth yellow card of the season.
"If he is getting clipped and going down in the box, no problem. But if he is not getting clipped and is going down then it is stupidity because he is in great areas to either cross the ball or shoot. So he has got to have a little think about that.
"I have to rely on Gary to tell me if he was clipped. If so, fine, but if not then I don't want to see that and, if you look at Gary's bookings this season, I think half of them have been for that - referees judging it that way."
Adams also has concerns with his defence providing very little opposition to Argyle's attempts to penetrate.
He described the third goal as 'calamitous' and intends to draft in loan cover to shore things up at the back.
He said: "It highlighted the areas I need to strengthen for next season and the areas we need to improve on for the rest of this."
