The Vancouver Whitecaps have been a pleasant surprise this season, becoming the top seed in the Western Conference halfway through MLS play. Vancouver qualified for the CONCACAF Champions Cup through their domestic Cup in Canada.

The Vancouver Whitecaps said a “significant number” of players who traveled to Mexico for last weekend's CONCACAF Champions Cup final have become ill.

The teamwide illness caps a disappointing week for the Whitecaps, who saw their impressive 15-game unbeaten streak across all competitions come to a crushing end with a resounding 5-0 defeat to Cruz Azul in Saturday’s Champions Cup final. Vancouver had been hoping to capture its first major continental trophy.
