Coach Steffen Baumgart from Bundesliga club 1. FC Köln was able to fall back on attacker Davie Selke and central defender Luca Kilian in training on Tuesday.
Selke was unable to take part in the goalless draw at Union Berlin on Saturday due to illness. Kilian suffered a torn muscle during the winter preparations and was not available for weeks.
A game by Kilian on Friday (8:30 p.m. / DAZN) against VfL Bochum at the bottom of the table is likely to come too early. FC are also missing the long-term injured Jan Thielmann, Mark Uth, Florian Dietz, Sebastian Andersson and Kristian Pedersen, who are completing a rehabilitation program.
