In early July, Poromaa fell during a roller-skiing session at Södra Berget in Sundsvall. He was taken by ambulance to hospital, and his father, Larry Poromaa, said his ankle was broken.
Now, just over five weeks after the accident, Poromaa is back. The 25-year-old was seen cycling in Torsby during the national team's pre-season camp.
William Poromaa, who had a tough season last year, including a rib injury that disrupted his Olympic training, will also hold a press conference on Wednesday.
