Norwich boss Alex Neil says he cannot "babysit" his players after the Premier League club began an investigation into keeper John Ruddy.
City are looking into footage which appears to show Ruddy in a scuffle in a city nightlife district on Sunday.
"You're in the public eye so you've got to try to be on your best behaviour at all times and you represent the club wherever you are," said Neil.
"Their actions will have direct consequences to what happens to them."
Neil added to BBC Radio Norfolk: "I can't go and babysit them, the responsibility falls upon them."
