Having joined initially on loan in late 2011, Francis’ first full campaign with the Cherries saw the club finish second in League One.
He played every minute of every game that season, a feat he almost repeated 12 months later, missing just 45 minutes of the 2013/14 season.
The defender was again a near-permanent fixture of Eddie Howe's backline last year.
