Crystal Palace have triggered the option in Jean-Philippe Mateta's contract to extend his stay at the club until 2027.
The Frenchman, 27, would have entered the last 18 months of his deal at the turn of the year with his current contract expiring in June 2026.
But sources with knowledge of the deal told BBC Sport Palace have used the option to keep him tied to Selhurst Park for another two and a half years.
The club are yet to officially confirm the news.
Mateta and the Eagles have been in talks about a new contract in recent months amid his goalscoring form.
