Rotherham have confirmed that Peterborough winger Daniel Kearns has joined the club on loan.
The 21-year-old had a spell on loan at League Two club York City earlier this season and has returned to the fourth tier with the Millers.
The Republic of Ireland under 21 international has experience at Championship level having featured 20 times for the Posh last season.
But manager Darren Ferguson has decided that Kearns is best served by continuing his development away from London Road.
Kearns began his career with Dundalk in the League of Ireland before moving to Peterborough in a three-year deal in the summer of 2011.
