Manager Owen Coyle has hinted he could give left-back Marcos Alonso a chance at Fulham on Saturday as Bolton look to arrest a run of four consecutive defeats.
Alonso has not featured for the Trotters since August after breaking his foot playing against Macclesfield Town in the Carling Cup.
However, the Spanish defender is nearing full fitness and could be included in Coyle's side to face the Cottagers, which would mean bad news for regular full-back Paul Robinson.
"He has come back from his injury and got two or three reserve games under his belt," the manager told the Bolton News.
"His training has improved no end. He's been in our squad every week but now he's getting closer to his maximum in terms of fitness.
"He got a freak injury in the cup tie against Macclesfield, there was no-one near him.
"But I've been happy with how things have gone with him, and Marcos is very much in our thoughts."
Bolton, currently sitting rock-bottom of the Premier League, have conceded 36 goals in their 15 games this season and have the worst goal difference of any team in the top flight.
Coyle could shake up his backline against Fulham in a bid to plug the Trotters' leaky defence, with Icelandic stopper Gretar Steinsson also in contention for a start.
The manager admits injuries and suspensions have prevented him from switching around his line-up earlier in the campaign.
"Confidence is king, as you know, and a lot of this is letting the players know that you still have the belief in them," he said.
"I think we have been very loyal - some would say too loyal to certain players. But sometimes circumstances dictate that they get more opportunities than their performances merited.
"If you do have a number of personnel missing, you can't chop and change as you'd like."
