The 21-year-old American landed awkwardly on his left shoulder after an aerial duel with Frankfurt forward Bas Dost in the 10th minute. "Weston dislocated his shoulder. He's still in the hospital," Schalke coach David Wagner said after his side's 1-0 win. "It still needs to be decided whether he needs an operation or not. But he will definitely be out for some time."
McKennie had been a regular presence in Wagner's team, playing in all but two of its Bundesliga games this season.
