Jenas failed to train today after collecting a knock on his toe while Berbatov is nursing an ankle injury.
Both players were on the scoresheet in their 2-0 win over Sheffield United and Jol remains hopeful they will recover in time.
Jol added: "Berbatov got a knock on his ankle but hopefully he will be okay.
"JJ did not train because he had a problem with his toe. We will have to wait and see but hopefully he will be available."
Dutch winger Arjen Robben - injured in the warm-up before the Middlesbrough game - and Michael Ballack should both be in contention for a place in the side on Sunday.
