Ghanaian youngster Kelvin Ofori has been ruled out of action for eight weeks after suffering an injury while training at Paderborn.
The former Fortuna Dusseldorf player tore a ligament in his knee and will now be out for six to eight weeks.
Ofori missed the season opener against Karlsruher, a game Paderborn won 5-0.
The Right to Dream Academy graduate struggled with injuries in his first campaign with Paderborn and was hoping for a good season.
However, the injury setback means the young winger will spend time on the sidelines.
The 20-year-old will miss games against former club Fortuna Dusseldorf, Hannover, FC Kaiserslautern and Holstein Kiel.
