The forward has been out of action since September with a hamstring injury and has suffered setbacks during his recovery after pushing too hard in training.
Moore is awaiting confirmation that Tulloch will be able to return to training, details on the programme and whether the youngster will carry that out with West Brom, or return to Rovers for the first time since his injury.
But the Rovers boss also suggested that he will consider opting against continuing Tulloch’s loan into the second half of the season should his absence be prolonged further.
“It’s dependent on the news with Rayhaan but before seeking new targets we want to see what is going on with him,” he said.
“That’s the position that we’re in at the moment.
“The latest update on Rayhaan is they’re just deciding on medical terms whether to release him back or just do a bit more work on him to make sure.
“He’s fine. He’s okay.
“We’ve detected a bit of fluid in the hamstring, which in a sense is quite good really.
“It’s just the boy’s body dispersing that itself, so it’s quite good news really.
“It’s a younger player that has pushed his body to his limits and his body has created that fluid to protect his body.
“A medical decision has got to be made on that and we’re just waiting on the conclusion.
“With that comes a training programme which could either be done with us or potentially done there.”
