Swindon manager Paolo Di Canio says he will not play goalkeeper Wes Foderingham again until he apologises to fans for the "arrogance" he showed in the 4-1 loss at Preston.
The 21-year-old was substituted on 21 minutes after his error led to Akpo Sodje's opener.

He exchanged words with Di Canio as he left the field and chose to sit in the stands for the remainder of the game.
"He's the worst professional I've ever seen," Di Canio told BBC Wiltshire. "It wasn't only the mistake, which can happen to everyone. It was the arrogance later on when he started moaning to the others. That was the worst thing for me.
"If he doesn't come out and say sorry to the fans for his professionalism, then he is out of my team."
