Jem Karacan has penned a new three-year deal with Reading.
The Royals confirmed last week that talks over an extension were progressing well and Karacan has expressed delight at penning fresh terms.
"I'm delighted to finally get it done, we've been in negotiations for a little while so it's nice to put pen to paper," Karacan told Reading's official website.
"Ever since I arrived, I've always wanted to become a first-team regular and in the last couple of years I've managed to do that - to come through the ranks has been brilliant."
