England won 1-0 in Iceland in a a controversial end to the Nations League encounter.
Raheem Sterling scored a late penalty in injury time, before the hosts were promptly given their own opportunity from the spot.
As the referee spoke with Raheem Sterling, penalty taker Birkir Bjarnason and Three Lions goalkeeper Jordan Pickford, television footage seemed to show Ward-Prowse stamping on the penalty spot with his studs.
But Ward-Prowse, who was winning his third cap, claimed he was just trying to delay the game and insists he didn't break any rules.
He said: "It wasn't any digging of the spot, it was more just delaying the penalty.
"It was a bit of a mad few minutes. We'd just obviously scored what we thought was the winning goal and then we faced the penalty, so it was more a delaying tactic just for everyone to get their heads together and prepare for the penalty.
“Thankfully it went in our favour."
