Heavy snowfall and freezing conditions had also caused two Bundesliga matches to be scrapped this weekend.
"The Bundesliga fixture between HSV and Bayer 04 has been called off due to weather-related safety concerns at Volksparkstadion. We’ll keep you updated on the new date," Leverkusen posted on X.
Fourth-placed Leverkusen visit Hoffenheim on Saturday, when Hamburg host Borussia Moenchengladbach.
