Foderingham kicked a water bottle and stormed down the tunnel after he was replaced 22 minutes into Swindon's 4-1 defeat, but Di Canio has revealed that the goalkeeper has said sorry for his outburst.
Di Canio told the club's official website: "Wes has apologised. The situation is now clear and we will move on and work together.
"He is a genuine guy and a strong character.
"The rules are there and he will pay his price for his actions. He has been fantastic for us last and this season, but he didn't behave well on Sunday."
Di Canio also revealed that Foderingham would be available for selection when Swindon play rivals Oxford United on Wednesday night.
