In the 2005–06 season, Wolf recovered from injury and found himself competing over a centre–back position with Thomas Paulus and Bartosz Bosacki. After featuring in three matches since his return in September, he suffered an injury that kept him out for a month. Following his recovery from injury, he returned to the first team, but was plagued with another injury. Wolf again returned to the first team and finished the season making 22 appearance in all competitions. During the season, he signed a contract extension with the club, keeping him until 2009.
