Juan will be involved," said Carey. "He is desperate to play.
"He is just short of games at the moment but he's coming back and he will be back scoring goals for us."
Eifion Williams is also likely to miss out after limping off with a thigh injury.
So Carey could be forced to play 26-year-old Ugarte.
"I just think he needs more games," he said. "He may be pushed a little bit sooner because we are without Proctor and Llewellyn, but that's out of necessity.
"We will have to wait and see on Eifion Williams."
