The Sun tabloid alleged Manchester United forward Rooney drunkenly gatecrashed a wedding at England's hotel in Watford, north of London, on Saturday.
Rooney started England's 3-0 World Cup qualifying win over Scotland on Friday, but suffered a knee injury that ruled him out of Tuesday's 2-2 friendly draw at home to Spain.
A statement issued on Rooney's behalf, said he was sorry the pictures had been published and accepted the images were "inappropriate for someone in his position".
Jones, asked about Rooney's situation on Thursday, jokingly said: "He had a good night, he had a very good night!"
The England rugby squad are currently based at the Pennyhill Park Hotel in Bagshot, southwest of London, while they play four end-of-year internationals at Twickenham.
Jones, speaking at Pennyhill Park on Thursday ahead of England's match against Fiji this weekend, was asked if he would impose a curfew on his squad.
"They are adults," he said. "Most of the players have got their own families.
"They'll come back here, they'll have a few beers and they'll decide when they go to bed."
The Australian added: "The time we have to have a curfew is the time we don't have a leadership group within the team.
"We've got a great leadership group within the team so we don't need to have curfews."
Interim England football manager Gareth Southgate, still waiting to discover if he will be appointed on a full-time basis, said there was a need to review how the national team's players spent their free time.
"Over the last few years, the players have been allowed to go home during a period of time," Southgate told reporters after the Spain match.
"They trained Saturday morning and they trained again on Sunday afternoon, and I gave the players a period of time off (in between). I'm not aware of anything else.
"There were lots of changes we made to routines. Some things we thought we should keep the same and I'll have to review (it) -- or maybe I won't have to review! Someone will have to review it."
