Wigan have completed the signing of defender Steven Caldwell on a free transfer.
Caldwell, who turns 30 next month, was released by Burnley at the end of the season following their relegation to the Championship and, after a spell training with Bolton, went on trial with Wigan.
He featured in their pre-season friendly victory over Dundee United and has now agreed a one-year deal at the DW Stadium, joining up with brother Gary.
"Gary has of course told me what the club is like and how impressed he has been with the set-up here, and I am delighted to have sorted out my future now," he told the club's official website. "I have already got to know the lads over the past few weeks and I can't wait to get started and fight for my place."
Boss Roberto Martinez added: "We have seen what Steven is all about during his time here - a leader on and off the field - and he is a great personality to have in the dressing room. He has shown real professionalism in his time with us and we are delighted to have him on board.
"He has good experience of the Premier League and has played in the Champions League and UEFA Cup plus is a full Scotland international. He is a totally committed defender who will add fantastic competition to the squad."
Caldwell began his career at Newcastle before joining Sunderland in 2004 and then moving on to Burnley three years later.
Meanwhile, Ipswich Town have completed the signing of Wigan striker Jason Scotland on a one-year deal. The Championship club have paid an undisclosed fee for a player who scored one goal in 32 league appearances last season.
Scotland said: "I am delighted to have joined Ipswich and look forward to trying to help the club get into the Premier League."
