Scott Laird (pictured) was celebrating on the pitch with team-mates and fans following the League Two side's historic 3-1 victory over Newcastle on Saturday when a fan ran over to him and laid him out with a single punch.
And Tuesday's Sun reports that Laird was smashed in the face by 24-year-old Rob Fitzgerald, current boyfriend of stunning blonde Jade Coles. She claims that Fitzgerald thought he was "protecting her honour".
Fitzgerald was charged with common assault and pitch invasion on Tuesday. He has bailed to appear before magistrates on January 26.
"I haven't been in a relationship with Scott now for two or three years but Rob knows about it," Coles explained to The Sun.
"Scott was a player and I don't mean on the pitch. He was a bit of a ladies' man.
"Rob was at the game celebrating the victory on the pitch. He saw Scott celebrating and just lost his temper.
"He'd been drinking and that's why it happened. He was being protective. It was a moment of madness."
Laird had shrugged the punch off at the time, saying, "it was a fantastic day for everyone at Stevenage and I don't want to let the incident take the gloss away".
