Preston full-back Darnell Fisher has been handed a three-match ban after grabbing an opponent's genitals, the Football Association has announced.
Fisher was found guilty of violent conduct by an independent regulatory commission in relation to an incident involving Callum Paterson during the Sky Bet Championship match against Sheffield Wednesday on November 21.
The incident was not seen by the match officials at time but was spotted on video afterwards, the FA said.
Fisher had denied the charge in relation to the incident, which occurred in the 62nd minute of the match.
Pulis was asked about the incident during his pre-match press conference on Friday ahead of the match against his old club Stoke.
"I think what the lad did was ridiculous really," he told reporters.
"Did he do it for Callum to react and try and get the kid sent off? That's the only reason I can think why he did it.
"But it is ridiculous and something that should not happen in professional sport and fingers crossed we won't see it again."
Blackburn's Lewis Holtby jokingly covered his genitals as Fisher passed him when the sides met at Deepdale on Tuesday night.
