Bolton boss Owen Coyle wants defender Jlloyd Samuel to play another two reserve matches before being considered for a first team comeback.
Samuel has not played for Coyle's side since a pre-season friendly with Osasuna in August due to a ruptured thigh.
"Jlloyd did very well to come back and play through the reserve game given he had been out for months," said Coyle.
"He's back training with the group, but he's only had one reserve game, so he's certainly not in contention to face Newcastle.
"However, he is progressing, which is great because he's a terrific lad as well as a top player.
"We hope that with another couple of reserve games then he'll be right back in the mix.
"That will be great because the loss of Zat Knight (knee) and Sam Ricketts (Achilles), who have been hugely influential as part of our group this season, were big blows."
