Topsy Ojo and Mike Brown have been found guilty of misconduct following a Rugby Football Union investigation into England's tour of New Zealand.
Jeff Blackett, the RFU's chief disciplinary officer who conducted the inquiry, has found David Strettle and Danny Care not guilty of misconduct.
Ojo was fined £500 and reprimanded after he was found to have stayed out all night.
Brown was fined £1000 and reprimanded after also staying out all night and arriving late for a physiotherapist appointment.
Ojo, Brown and Care were at the centre of sex allegations following England's 37-20 defeat by the All Blacks in Auckland.
But no official complaint was made against the players, who denied any wrongdoing.
Blackett said in today's report: "All the players I have interviewed vehemently deny any criminal wrongdoing.
"I have seen or heard no evidence which has been tested to gainsay those denials."
Strettle was not in the list of people the New Zealand police wished to interview, Blackett said.
Explaining the sequence of events that led to the complaint being made, Blackett said: "Mike Brown and Topsy Ojo (together and with some other players) visited a number of bars in the early morning after the first Test match.
"They met the complainant and she eventually accompanied them back to the team hotel some time after 0700 on Sunday morning. She went to Brown’s room and was there alone with her.
"At about 0835 Brown left the room and attended a physiotherapist appointment and while he was there, Topsy Ojo (who had gone to the room to ensure Brown went to the see the physiotherapist) was in the room alone with the complainant.
"Danny Care had returned to the hotel at sometime between 0130 and 0300. David Strettle had returned to the hotel at sometime between 0330 and 0500.
"Care and Strettle popped their heads round the unlocked interconnecting door of the room at about 0855 and saw Ojo with the complainant. They were there for no more than a few seconds.
"Brown admitted that he was a bit tipsy while in the bars, although in control. He also accepts he was 20 minutes late for his physiotherapist appointment in the morning.
"All of the other players admit modest, but not excessive, alcohol consumption and they all attended their morning physiotherapist appointments on time.
"They believed that they could relax a little more than normal because the day following the Test match was a travelling day."
Brown was found guilty of misconduct in that he stayed out all night during an England tour and as a consequence was late for a physiotherapist appointment.
The Harlequins full-back was fined £1000 and warned in future not to put himself in any compromising situations which may lead to him bringing the game into disrepute.
Ojo acknowledged that he should not have stayed out until after 0700 but did attend his physiotherapy appointment on time.
