The American collided with James Rodriguez in his side's 2-0 defeat to the Bundesliga champions and was carried off the pitch in tears.
Schalke midfielder Weston McKennie looks set for an extensive injury layoff following the seemingly serious leg injury he picked up in a challenge with Bayern Munich’s James Rodriguez in a 2-0 defeat against the German champions.
With Bayern 1-0 up in the 51st minute, the American and Bayern goalscorer Rodriguez competed for a loose ball and the latter caught the former’s left shin, sending him tumbling to the turf in obvious pain, before he had to be carried off the field in floods of tears, to be replaced by Nabil Bentaleb.
