Canada men's national team coach Jesse Marsch expressed outrage Friday, saying Vancouver Whitecaps players had been "poisoned" during their visit to Mexico for the CONCACAF Champions Cup final. But Whitecaps head coach Jesper Sorensen said he doesn't believe someone intentionally got his team sick.

The Whitecaps canceled practice Wednesday and had a modified session for cleared players Thursday after players and staff reported gastrointestinal symptoms. The Whitecaps are scheduled to play the Seattle Sounders in a Cascadia Cup rivalry match at BC Place on Sunday.

The Canada manager was not thrilled about the shape of three of his players following the Concacaf Champions Cup final
