Bayern Munich will check on Leon Goretzka and Joshua Kimmich ahead of their final Bundesliga match before the winter break against Wolfsburg.
The midfield pair missed the weekend win over Stuttgart with illness and they are still being monitored.
Goalkeeper Sven Ulreich is not fit to return to the squad so Daniel Peretz will continue to deputise.
“We hope there are no more ill players,” Thomas Tuchel said on the club’s official website. “It’s an hourly update with Leon Goretzka and Joshua Kimmich. It’ll be tight for both. We think the rest are fit.
“It looks like Daniel Peretz will be in the squad again with Ulle not yet back.”
Bayern are guaranteed to go into the winter break in second position in the Bundesliga table following an excellent first half of the campaign by Bayer Leverkusen.
They will have work to do if they are to claim a 12th title in a row, but Tuchel wants his side to finish on a high.
“Our work is always about looking ahead,” he added. “A lot has happened this year. We’re making good progress and are trying to meet our tasks.
“We want to continue developing our team. It’s all good and we’re looking forward to a break. But we want to take the next step in Wednesday’s game.
“We want to be better in possession. Wolfsburg have different tactics from Stuttgart. We’re again expecting a back five.
“We want more of the ball and will now take on a new task. It’s down to us. How good are the movements and distances? Let’s see what challenges the game brings. We hope we can have the right answers.”

Tuchel is keen to temper expectations of teenager Aleksandar Pavlovic following his breakthrough in the team in recent weeks.
The former Chelsea boss said: “We knew before that we have Aleks and what he can do. He was always good in training. It helps nobody if Aleks is our solution in that position now at 19.
“We’ll do everything that makes sense for the club and youth development. We’re the biggest fans of our own youth players from the Campus. Aleks has earned it with the way he is and how he trains. It’s good if we don’t overpraise someone.
“It’s good what he’s doing. He always has a smile on his face and is very grounded. Quality always comes through.”
