Barnsley have made centre-back Robbie Cundy their third signing of the summer transfer window.
The 25-year-old joins the Reds for free, on a two-deal deal, having turned down a new deal to stay at Championship club Bristol City.
Cundy spent time at Aston Villa and Oxford United as a youngster before spells in non-league with Gloucester and Bath.
He joined Bristol City in 2019 and was loaned to Exeter, Torquay, Cambridge and Gillingham – suffering a serious knee injury with the latter which kept him out for year.
The tall defender finally broke into the Robins team earlier this year, making 14 Championship appearances including in a 2-0 loss at Oakwell in March.
Cundy follows goalkeeper Jamie Searle and midfielder Luca Connell who joined the Reds late last week.
