The player is Mohamed Aboutrika -- who was an absolute STUD before retiring in 2013. In fact, he was named African Footballer of the Year FOUR TIMES!
But now, Egypt is putting the screws to Mohamed -- after officials say he helped finance the Brotherhood.
FYI, Egypt has designated the Muslim Brotherhood a terror organization. American politicians have introduced legislation to deem it one in the U.S. as well.
For his part, Mohamed DENIES the allegations and his lawyer says he will appeal.
