With Manchester City's Joe Hart still troubled by a back injury, additional attention will now be paid to Ruddy's performances at Norwich to give Hodgson a bit more information on a keeper whose presence in Switzerland was overshadowed by Jack Butland's confirmation as the youngest goalkeeper in England history.
"Forty-five minutes is a small sample to make a decision on but he showed a lot of composure and a lot of character," said Hodgson.
"What we have to do now is watch him very closely.
"There won't be a Norwich match he plays where I don't get a good report because we need to get a better grip on how he is as a goalkeeper.
"When I selected him for Euro 2012 it was a fairly quick decision based on not an awful lot of knowledge."
