Shaun Cummings has agreed a new contract with Reading that will keep him at the Madejski Stadium until 2015.
Cummings, 23, who made his name at the Chelsea academy, helped the Royals win last season's Championship title and the defender has made six appearances in the Premier League this season.
"I'm very excited to remain at a club that has such ambition in the Premier League,'' Cummings told the club's official website. "To have already played against the likes of Man United and Liverpool is great experience at my age. I can't have asked for anything more.
"Everyone at the club wants to fight for their shirt and play in the Premier League and everyone knows what we've got to achieve to stay here.''
