However, the Potters centre-back - who left the field in tears following his dismissal - has stated there was "no malice" and has been defended by team-mates and other figures in the game, including his former boss at Manchester United Sir Alex Ferguson.
"Sir Alex rang me after the Carling Cup final, which was good of him, and we had a good chat and that was just something to lift my spirits," revealed Shawcross.
"That is the man he is and he is a fantastic manager and even when you leave he keeps in contact and makes sure you are all right."
Both Shawcross and Stoke manager Tony Pulis contacted Ramsey following the injury and the defender says he has put the incident behind him.
"When you hurt somebody it is not nice," added Shawcross. "But it was unintentional and I've moved on from that. Hopefully Aaron will get back fit soon."
Ramsey underwent surgery to fix fractures to the tibia and fibula in his right leg soon after the match at the Britannia Stadium.
Ryan has been going into tackles in training and he's been fine, he's been bombing around and doing extra work. It won't make any difference to him and I'm delighted to have him back
Stoke boss Tony Pulis
There is as yet no timeline set for the 19-year-old Welsh international's return but he has vowed to come back "fitter and stronger".
Shawcross, who was an unused substitute for England's 3-1 international friendly victory over Egypt at Wembley on 3 March, has a minor ankle injury which may curtail his involvement against Tottenham.
But if he is fit Pulis says he has no qualms about putting him straight back in the side.
"I think everyone who has seen the incident, apart from maybe one person [Arsenal manager Arsene Wenger], recognises it was an accident," the Stoke boss said.
"Ryan has been going into tackles in training and he's been fine, he's been bombing around and doing extra work.
"It won't make any difference to him and I'm delighted to have him back.
"He is a very level-headed kid. He's been captain of this team this season and, at that age, I think that shows he has good character."
