Rochdale have signed defender Niall Canavan on a two-year deal after he was released by Scunthorpe.
The 25-year-old moved to Dale on loan towards the end of last season and scored once in his 11 appearances.
The former Republic of Ireland Under-21 international made 173 appearances for the Iron.
Canavan is boss Keith Hill's first signing ahead of next season after losing defenders Ashley Eastham and Olly Lancashire.
