- Tah to miss out against Hertha on Matchday 32.
- Germany international suffering from a virus.
- Leverkusen six points and one place ahead of Hertha in the standings.
The Hamburg native, who has missed just two league games this season, had helped Bayer keep five straight clean sheets before Matchday 31's 3-2 win at FC Schalke 04. His absence will likely mean that Brazilian utility man Andre Ramalho comes in to deputise alongside senior centre-back Ömer Toprak, with left-back Wendell also missing.
Meanwhile, Hertha have their own defensive worries after USA international John Anthony Brooks was ruled out of the trip to the BayArena with a shin injury. The Berliners, one place and six points behind third-placed Leverkusen, currently hold a one-point cushion over Borussia Mönchengladbach in their bid to claim the final UEFA Champions League spot.
