Brett Holman and Darren Bent are both in contention for Stoke on Saturday.
Holman missed the Liverpool game with a hamstring problem while the Reds clash came just too soon for Bent, who had been struggling with an ankle injury and a virus.
But both are firmly in the frame for the Britannia Stadium encounter.
Andreas Weimann, who limped off against Liverpool, has returned to training.
However, Ciaran Clark is a doubt.
The centre-half picked up a shoulder injury in the international clash with Austria when he was away with Republic of Ireland and subsequently missed the Reds clash.
Lambert said: "Ciaran has still got a little bit of a problem. We'll see how he is the rest of the week.
"But he's still got a problem with his shoulder. He is still a doubt.
"Darren has trained every day. He will be in the squad.
"Darren had that month or so off when he couldn't do anything with his ankle.
"But he is back fit now and trained again this morning and is in the squad.
"Brett hasn't been getting in because Charles has been playing extremely well.
"He wasn't fit for Liverpool. He is fit now. He has trained this week so he is back in the fray."
Lambert also revealed that there is still no light at the end of the tunnel for Richard Dunne, who has thus far missed the entire campaign.
