St Pauli call up press officer against Hanover
Hauke Brueckner, 30, who works as a press officer for the alternative Hamburg club and plays for the under-23 team, received a call from coach Holger Stanislawski who told him to turn up at training "in one hour".
"Against Hanover we only have four fit defenders so it makes sense to bring in Hauke," Stanislawski said.
Brueckner, who played 10 games in Germany's second division in the 2002/03 season, said his new team mates were surprised to see him.
"When I walked into the changing room with my bag, the boys were staring at me, not really believing it," Brueckner told the club website.
"They did crack some jokes but I know them well and after that everything was good," he said.
