The 18-year-old forward was already invited for the Kings' rookie camp and will now also attend the main camp of the NHL team.
The defenseman was drafted earlier this summer and already participated in their development camp.
Besides captain Nico Hischier and Jonas Siegenthaler, the goaltender will be one of three Swiss attendees.
After 13 years of playing professional hockey in Switzerland, the defenseman will hang up his skates.
The two teams are apparently very close to an agreement regarding the goaltender.
