Both forwards have been signed to one-year contracts and will thus stay with the Lions until the end of the 2021-22 season. David Baumann and Nico Lehmann are both products of EHC Kloten's organization.
Baumann recorded one goal in 33 regular-season games for HC Thurgau last season. Lehmann, too, was able to play a couple of games in the Swiss League: he appeared in seven games for EHC Winterthur. However, he mostly suited up for Kloten's U20 team (eleven goals, 23 assists in 30 games).
