Goalkeeper Craig Gordon has agreed a new three-and-a-half-year deal with Celtic.
The 34-year-old Scottish international now remains at Celtic Park until the summer of 2020.
Gordon has made over a century of appearances for the club since arriving in 2014. That followed a couple of years out of the game with knee problems.
In January, the Scottish Premiership leaders rejected a couple of offers from Chelsea for the former Hearts and Sunderland keeper.
Having made his international debut in 2004, Gordon has since appeared 45 times for his country.
