Gelsenkirchen shook hands with experienced goalkeeper Timo Hildebrand. The contract will come into effect after a medical check-up.
The 32-year-old footballer wore the jerseys of Lisbon's Sporting last season and has been a free agent since the summer.
Schalke made this decision after the main team goalkeeper Ralf Fahrmann suffered a serious injury. The coach was left with two choices: young Lars Unnerstall and veteran Mathias Schober.
Throughout his career, Hildebrand has represented clubs such as Hofheim, Stuttgart, Valencia, and Hoffenheim.
