Mirko Filipović will have examination of testicles, injured in his fight with Alistair Overeem. Crocop still feels great pain, said his doctor.Mirko will undergo examination to found out if there is danger of complications, such as torsion of testicles and inguinal hernia. Mirko also returned home with pain in his right knee, which was recently operated.I advised him to postpone his next fight till New Year, but he insisted on this term. The main problem is that he cannot rotate this knee too much, and without rotation there is no devastating high kick, which is Mirko well known for. He even didn't try to return to stand up fight from the ground, cause he was afraid to make a wrong step and injure the knee, explains dr Kapulica.
