Gumprecht, whose contract with the Mariners expired today, will join the Lions and is expected to make his debut against the West Sydney Berries on May 10, once the state league's transfer window opens on May 5.

The 33-year-old German midfielder is currently taking legal action against the Mariners regarding elements of his expired contract. The move ends his three year involvement with the club where he was voted Mariners Members' Player of the Year in 2005/06.
