Gabby Agbonlahor and Andreas Weimann are doubtful for Saturday's clash against Cardiff City.
Agbonlahor is still struggling with the ankle injury that kept him out of last weekend's goalless draw against West Ham.
And fellow striker Weimann limped off with a hamstring problem in the stalemate at Upton Park.
Antonio Luna and Joe Bennett also remain concerns, while Lambert will assess Fabian Delph who missed the West Ham game through illness.
"I've got a few lads that are still struggling," said the Villa boss.
"It is the same lads as last week and we will have to see how Andi is as well.
"Andi is a doubt with his hamstring. I will have to see tomorrow how Fabian Delph is."
