Danny Collins has signed a new two-and-half-year contract with Sunderland.
The defender is now committed to the Black Cats until the summer of 2011.
The 28-year-old is one of the Wearsiders' longest-serving players, having joined the club from Chester in 2004.
His versatility has made him a vital part of the Sunderland squad, as he is able to operate at either centre-half or left-back.
Having spent the best years of his career in North East, Collins is delighted to have been allowed the opportunity to extend his stay at the Stadium of Light.
"I'm happy here and it is good to sign for a few more seasons. I think the club is going places," he told Sunderland's official website.
