The Ivory Coast-born Danish defender, who joined from FC Nordsjaelland in the summer, has been sidelined since rupturing ligaments in his knee in September.
21-year old Okore has been working hard to get back to full fitness and Lambert suggested he could feature for Villa within the next month.
"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."
