Former Tottenham midfielder Eles Fanning has pleaded guilty to assaulting a colleague’s daughter, the Crown Prosecution Service said.
Fanning, 28, will serve three years’ jail and will also pay £30,000 in victim surcharges.
He was also ordered to pay a victim surcharge of £15,000 and must complete 400 hours of unpaid work.
The footballer’s lawyer said his client had been “scared to death” of being charged with assault.
“I am not going to speculate about the case, I have never been involved with such a terrible case,” he said.
The court heard the woman had been playing on the same team as Fanning when the incident took place in May last year.
She was taken to hospital after suffering a broken nose and a concussion.
She returned home on July 5, 2016, and the following day he allegedly assaulted her in his hotel room.
“She was so frightened of him that she went straight to the police,” her mother, Julie Hines, told the court.
She said the woman, who cannot be named for legal reasons, was also “very upset” about her son’s alleged actions.
Fanner is expected to be sentenced in the Old Bailey on September 28.
He has admitted assault occasioning actual bodily harm.
He had been suspended from his club for two months pending the outcome of a court case.
In March, former England international Ashley Cole was jailed for eight years for his role in the attack.
Cole was in court for the first time in five months, when he pleaded guilty in November 2016 to an assault charge and was fined £400.
In May, he was released from prison after serving 10 months for a previous assault conviction.
