"Jores is doing great at the minute," Lambert said on the club's official website. "I think he is in a good place at the moment with his knee.
"Hopefully with a bit of luck he won't be too far off.
"He won't be in the squad for a few weeks but he's come back quicker than we actually thought.
There was also positive news regarding striker Libor Kozak, who broke his leg in training last month.
"Kozak is doing well too from his point of view," Lambert continued. "So the long-term ones are starting to get there but it's still a bit too early."
