French international Lucas Hernandez has been told he must serve prison time for breaching a restraining order following a domestic violence incident.
The Bayern Munich star had appealed to have his six-month jail term suspended.
But on Wednesday it emerged a Madrid court had rejected his appeal - and given him 10 days to enter prison voluntarily from 11am on October 19.
Lucas, 25, will be told he can choose the Spanish jail where he wants to serve out his six-month prison sentence when he attends the sentencing court in Madrid next week.
The shock news comes just three days after the left-back, who used to play for Atletico de Madrid, won the UEFA Nations League final with France when they beat Spain 2-1 with a late Kylian Mbappe goal.

The footballer was handed his prison sentence in December 2019 after breaching a restraining order preventing him from going near his then-partner Amelia Lorente.
He was told he could not go within 500 metres of the pretty brunette for six months, and sentenced to 31 days community service in March 2017 after being convicted of a domestic abuse charge.
His partner received the same punishment.
Lucas was arrested on June 13, 2017 at Madrid Barajas Airport as he got off a flight from Miami with Amelia following their honeymoon in the States. She reportedly escaped arrest at the time after she proved she had not been informed about the restraining order.
The Marseille-born defender, capped 29 times by France at senior level, lost his appeal against the execution of his prison sentence because he is not a first-time offender in Spain.
A spokesman for the judge who turned down Hernandez's appeal against his prison order, confirming he had been told he must serve his six-month sentence, said on Wednesday: "Madrid Criminal Court Number 32 has refused the suspension of his six month sentence.
Hernandez must now voluntarily enter prison in the next 10 days
"And it has told him he must attend court at 11am on October 19 so he can be informed he must enter prison voluntarily within ten days starting from that date."
Hernandez and Amelia married in Las Vegas in the summer of 2017 despite being told they must stay away from each other following the domestic violence incident.
They are thought to have tied the knot in secret on June 2 that year and went on to have a son together.
In March 2019 Amelia revealed on social media they were no longer together. She said at the time: "A mother always thinks twice, once for her and another time for her son.
"Only you and me my baby."
It is understood the footballer has launched a final appeal against the Madrid court decision which has yet to be ruled on.
The appeal will be considered by judges at Madrid's Audiencia Provincial Court.
Local reports say he will be expected to attend court next Wednesday to chose the prison he wants to do his time in, but could be spared having to enter jail at the last minute if appeal judges decide to uphold the appeal.
