Sonko has signed a two year extension to his contract which will keep him at his Madejski Stadium home until the end of the 2009/10 campaign.
Since signing from Brentford in the summer of 2004, 25 year old Sonko has made 110 appearances for the Royals and has undoubtedly been one of Reading`s most important players so far in their first Premiership season.
Following the record breaking season of 2005/06, Sonks was voted into the PFA Select XI for the Championship and regularly gained rave reviews.
Reading chairman John Madejski said, ‘Ibrahima is a vital player for us and I am delighted that he has agreed to stay here until 2010.
‘He is an exceptionally good defender and an equally important presence off the pitch, and he will play a central role in our continued development in the next few years.’
