The rookie West Brom winger, who has been on loan at Prenton Park since December, is nursing a knee injury and will miss the final 10 games of the campaign.
Parry was looking to make one last loan signing to cover for Elford-Alliyu's loss but failed to seal a deal before Thursday`s 5pm deadline.
Elsewhere, Rovers` injury problems have begun to ease and Parry will be reluctant to make changes following last weekend`s 1-0 home win over Colchester.
The result ended a seven-match winless streak and Parry said: "We are getting the right kind of response from the players."
