"I look forward to another fantastic weekend with the team and go there with the same attitude as to Höljes - to do my best together with a good team," says Ekström according to a press release.
Ekström, world champion 2016, is second in the championship after the two initial competitions, two points behind leader Johan Kristoffersson.
Ekström has replaced the lightweight Janis Baumanis who did not get his finances together due to the coronavirus.
