Bayern Munich star Alphonso Davies left Canada's CONCACAF Nations League third-place play-off against the United States men's national team after just 12 minutes on the pitch in California on Sunday.

Davies initially appeared to have injured his left ankle, but may have been receiving treatment on a more serious leg.

The 24-year-old left-back immediately made his way down the tunnel in what's a worrying development for both Canada and Bayern.

Davies has made 31 appearances for Bayern this season. Bayern hold a six-point lead in the race for the Bundesliga title and will next face Inter Milan in the UEFA Champions League quarter-finals.

Niko Sigur replaced Davies for Canada on Sunday. Bayern's other options at left-back are Raphael Guerreiro and versatile right-back Josip Stanicic.
