no they were Bundesliga clubs (St. Pauli and Werder Bremen)
We had an uncharacteristic massive snow-dump over the northern part of Germany. Normally it is not affected, but it was a huge storm, dumped a lot of snow, then froze. The pitches could probably have been made playable but travel was impossible - no trains for a few days and it took time to get the Autobahns cleared.
Frankly i would have been ok with our match being postponed, i couldn't feel my feet for most of the match. Thank goodness they sell Glühwein in the winter months!
