Benteke has endured a heavy schedule and played in all four of Villa's games over Christmas and the new year.
Lambert said: "I'd like to rest Christian because he's played a lot of games. He's played a lot of games for Belgium and his season with Genk had started before he joined us in August.
"But with Gabby and even Darren out injured, it has not been great. There have been a lot of injuries up front."
