The 31-year-old is a free agent following the expiry of his Stoke City contract.
Tony Mowbray: “Dean is a player with some options and he has some decisions to make.
“He’s been in the Premier League for six or seven years and will have an earning power that reflect that.
“He isn’t a player who the fans will necessarily get excited about but he can put out fires and he knows his job. He’s a player we potentially might have an interest in, but he might have some decisions to make.”
