Hibbard and Evans both made brief appearances in the friendly defeat against Bath last Fridaywhile Jones could be pressed into action following an injury to prop Dmitri Arhip.
But Tandy insists he has no qualms with giving the Trio an outing in Italy this weekend.
"It's great that these guys want to come back for us," said Tandy. "They're Lions and they love representing the region. They're huge for us and it stands us in good stead.
"Ian and Hibs are champing at the bit. Ian takes a bit of time to get there, so it (playing against Bath) was something he was keen to do.
"We feel it's part of his conditioning to get back into it, while Ian was really keen himself after coming back in real good shape.
"With Hibbs, it's a question of containing him. He says he'll be available, and if you give him 20 minutes he wants a bit longer.
"But the 20 minutes against Bath was part of his conditioning, so that's all he could have.
"Adam may be involved, potentially, we have plenty of options this weekend and Adam is one of them."
