Paris Saint-Germain said on Monday that they would take “appropriate action” after star striker Neymar failed to turn up for their first day of pre-season training.
The Brazilian forward has been linked with a move back to his former club Barcelona but was due back at PSG’s training ground on Monday.
A statement from the French champions noted: “On Monday 8 July Neymar da Silva Santos Junior was due to return to pre-season activities with the PSG senior squad.
“Paris Saint-Germain notes that Neymar Jr was not in attendance at the agreed time and place. This was without the club’s prior authorisation.
“The club regrets this situation and will therefore take appropriate action.”
In Rio, Brazilian media quoted Neymar’s father as saying that PSG “were aware” the striker would be absent.
“The reason (for his no-show) was known and planned for a year as part of his activities for the Neymar Institute (charity foundation),” said Neymar Senior.
He added: “We couldn’t postpone them and he will return (to PSG) on July 15.
“It’s as simple as that, no drama. PSG are aware and take part in the Institute’s activities.”
Neymar – who missed Brazil’s Copa America win in the last few weeks due to injury – joined PSG from Barcelona in August 2017.
He was banned for three games for lashing out at a fan during the French Cup final defeat to Rennes – and will also miss three European games for insulting officials after the Champions League defeat by Manchester United.
