Henderson did not travel with the Reds squad to Spain on Tuesday afternoon, for the second leg of their last-16 tie, due to illness.
Bajcetic, meanwhile, will not be available to feature at the Santiago Bernabeu as he recovers from an injury, Jürgen Klopp confirmed at his pre-match press conference.
“With Stefan, it is a stress response, which is absolutely bad. So, he doesn’t feel a lot, it’s only a little bit but he is now out for I don’t know exactly how long. We have just to let it settle then and we will see when he can come back.”
Klopp added: “[It’s] high up, around the adductor.”
