Preston striker Joe Garner is a marked man because of his physical reputation, according to boss Simon Grayson.
Garner was sent off after 19 minutes in the 1-1 draw with Wolves and North End have failed in an attempt to have the length of the three-match ban reduced.
The 27-year-old had only just returned from a one-match suspension after collecting five yellow cards in the opening 10 matches of the season.
"I certainly can't take away that edge that he has to his game," said Grayson.
"But when you look at some of the decisions that he's had against him this year in general play and bookings that he's got, there are other cases of players that have got away with miles more than Joe has."
Garner scored 27 goals in all competitions last season as the Lilywhites were promoted to the Championship, but he is yet to find the net this term.
"I think he's a marked man. I think people know what he does - he's obviously got to probably learn what he needs to do and what he can and can't do," 45-year-old Grayson told BBC Radio Lancashire.
"I'm not saying that referees are going into any game thinking 'I'm going to keep an eye on solely on Joe,' but they know his reputation and they do sometimes let other players get away with more lenient things."
