Asked if the incident could make the goalkeeper hesitant in future, Guardiola said: "I could understand that feeling if he felt that, but in today's training session there were two or three long balls and he was there. Of course that can happen but we will see."
Teammate John Stones has also been impressed with how Ederson, 24, has dealt with the situation.
Stones, speaking alongside Guardiola at the pre-match press conference on Tuesday, said: "Ederson has got on with it straight away.
"After the game in the changing room he was talking as if nothing had happened. That shows his character.
"He wants to be around the team, in that environment. Everyone has seen his face, the stitches, the swelling — but he's put a scrum cap on and he's been training today."
Two players who will definitely not feature are Yaya Toure and the injured Vincent Kompany.
Toure was left out of the squad by Guardiola and the manager raised fresh doubts over the veteran midfielder's future by refusing to make public why.
