Neil Lennon expects Eidur Gudjohnsen to sign for Bolton in time to face Reading this weekend and fellow veteran forward Emile Heskey could also sign if he impresses on trial.
Gudjohnsen enjoyed a stint with Wanderers between 1998 and 2000 before moving to Chelsea and has been training with Lennon's squad for almost a month.
The 36-year-old played 90 minutes for the club's U21s on Monday and Lennon confirmed the Icelander is set to sign a deal with the club until the end of the season.
"I'm assuming everything's agreed," the Northern Irishman said. "If there are any hold-ups it'll be a minor thing and I'm hoping to have him in the squad for the weekend."
Gudjohnsen may soon be joined at the Macron Stadium by Lennon's former Leicester team-mate Heskey, who was invited to train with the Trotters this week.
Heskey, also 36, is a free agent after leaving Australia's Newcastle Jets and Lennon has granted him a two-week trial period before deciding whether they will pursue a deal.
"Emile is a free agent, I know him very well from my time at Leicester and he's another player we tried to sign in our time at Celtic," Lennon said.
"He may be coming to the end of his career but he still has very good attributes.
“It's no-gamble stuff for us, we're just bringing him in and going to have a look over the next 10 days, two weeks - see if he's got something to offer.
"If he has we'll look at it, if he hasn't we'll say, 'thanks for coming in but we're not going to pursue this'."
