Ball set for Millers return?
Although there is no confirmation from either club, Posh manager Grant McCann told the Telegraph: "We had a disagreement over a team I selected."
The 21-year-old, who can also opperate in midfield, has made six appearances since joining Peterborough on loan in January.
The former Rangers loanee was signed by former boss Alan Stubbs in the summer and turned out 13 times for the Millers before agreeing a loan deal with McCann's side until the summer.
