Defenders Andre Bikey, Seb Hines and George Friend and midfielders Faris Haroun and Emmanuel Ledesma have all joined in with their team-mates again and will be assessed.
Asked if he was positive about their chances of facing Gianfranco Zola's men, manager Tony Mowbray said: "I think so. Some have a better chance than others but we'll be in a better position than we were last weekend.
"The injuries we've had were mainly strains and pulls and were only ever going to be 10 days or two weeks away. The ones who don't make this game should be available for the next one."
Andy Halliday had surgery on a broken nose in midweek and although he was expected to be fit for Saturday, he finished training early on Thursday and could be a doubt.
"It's just one of those delicate ones but it's not anything that stops him running and jumping," said Mowbray.
England U21 midfielder Josh McEachran is making good progress from an ankle problem but may not be ready to start a game yet.
"He trained today and did a little bit yesterday. Whether he's up to 100% speed we'll know tomorrow.
"I will chat to him. We'll have to check with him and decide whether he's best starting or ease his way back from the bench."
Chelsea have the option of recalling him from his season-long loan this month but Mowbray is confident he will be allowed to complete the campaign and assist with Boro's promotion push.
"Last week we had a conversation and they were 99.9% sure he was going to stay," Mowbray said.
"It depended on any injuries they picked up this week. At this moment it looks like Josh is going to stay, which is good for us."
Marvin Emnes is still not ready to return but long-term absentees Julio Arca, Muzzy Carayol and Curtis Main all are getting close to fitness.
"They're all out there with their boots on training with the physios," Mowbray said. "Curtis isn't too far from an U21 game.
"Muzzy may play in the U21 game after the one on Monday with a view to playing some part of the Aldershot game."
