Wanna see the toughest guy EVER?!?!
Meet Sia Soliola ... a star rugby player in Australia's NRL who broke his face mid-game -- but then had it repaired just a few days later with a handful of hardware no problem!!
The story is insane ... the 33-year-old Canberra Raiders player took an upper body shot to the face in the middle of a match last Friday and immediately knew something was wrong.
The clip is tough to watch ... Soliola gets hit right in the cheek -- and is forced to leave the game immediately.
