Striker Mark Robins who turned down the move to Tranmere earlier this week will now join them on a month's loan.
The transfer embargo still in place while the Reds are in administration means Glyn Hodges enquiry about the player could not proceed further.
Ironically, Robins is still expected to line up for the Millers Reserve team tonight against Barnsley if only for a 45minute run-out according to Rotherham's official website.
