Long is likely to make his debut in the derby with Bury on Saturday
Rochdale have signed Burnley defender Kevin Long on a one-month loan deal.
Long, 21, is new Dale manager John Coleman's first signing since taking over at Spotland earlier this week.
Coleman worked with Long at previous club Accrington Stanley earlier this season, with Long playing 24 games and scoring four goals for Stanley.
The Irishman also had two loan spells with the League Two side last season but is yet to make his first-team debut for his parent club.
