Mansfield Town sign defender Ryan Tafazolli

Mansfield Town have signed former Southampton defender Ryan Tafazolli.

Stags manager Paul Cox told the club's website: "We needed a physical presence in defence and Ryan is a player who does all the basics well.

"He is a young player who has a desire to progress, and has the ability to have a good future in the game."

Tafazolli, 20, passed through the Southampton academy before being released in May 2011. He played the end of last season with Cambridge City.
