Blackpool are waiting to hear whether striker Stephen McPhee will pick up a three-game ban following his red card in a friendly.
McPhee, 27, was sent off for violent conduct as the Seasiders were beaten 4-0 by Skonto Riga during their pre-season tour of Latvia.
The striker could now miss the first three games of the new Championship season should the referee include the incident in his post-game report.
"It's quite frustrating," said manager Simon Grayson.
"The referee could have decided to have give a yellow card, but instead decided to send him off.
"We don't want that to count to any official ban."
