The 29-year old Dutch centre-half has not played in the Premier League since the end of August because of a calf injury but is expected to be back for Saturday's meeting with the Toffees at Goodison Park.
"It's great," Villa boss Lambert said of the news.
"He went out of the team at a really good point for him, the way he was playing, and it was a blow for us that he pulled up injured.
"It's good to have him back, that's really good. If everything is all right then Ron will travel."
