Wrestler SUCKER PUNCHED after losing match in shocking scenes

A youth wrestler completely lost his head and SUCKER PUNCHED his opponent, with the police launching an investigation into the disgraceful incident.

A wrestler from Maine West High School and SPAR Wrestling Academy were pitted against each other at the 'Beat the Streets' tournament in Illinois.

Hafid Alicea of Maine suffered a 14-2 defeat to SPAR's Cooper Corder, with the bout descending into chaos following the result.

The referee pulled both contestants in to embrace as Corder extended his hand for a handshake.

But Alicea refused his rival's offering and sucker punched his opponent flush in the face, dropping Corder to the floor in a shocking moment.

According to TMZ Sports, Corder broke his nose following Alicea's brutal strike and will now have to wear a protective face mask in his upcoming wrestling matches.

The vicious hit, though, hasn't stopped Corder from training as he's already back in the gym ahead of his next contest.

Justin Pearch, SPAR Academy founder, said: "He is making the best of the situation and is already back to training.

"As you may know, wrestling matches can get heated but nothing leading up to the punch would give cause to such bad decision-making on the opponent’s part.

"It’s not tolerated in our sport and Spar Wrestling will never condone that behaviour."

TMZ Sport's report states the incident between Corder and Alicea is being investigated by the Oak Park Police.

The parents of both wrestlers are cooperating, per a spokesperson for the department.
