Loach recently returned from a loan at Rochdale and the summer recruit is heading back out to cover for Ben Alnwicks injury at Peterborough United.
Loach has only made 2 starts for the Millers and jumped at the chance to get some game time;
I jumped at the opportunity of coming to Peterborough, As a keeper, you need first team football and when I heard of the club's interest, it was a move I was keen to make. I have played against Peterborough a few times in my Watford days and they are a tough opponent." he told Peterborough's official website.
