Schalke midfielder Weston McKennie injured against Bayern
The 20-year-old American received an unintentional kick in the leg from James Rodriguez as he won possession from the Colombian star. While the free kick was awarded, McKennie was unable to continue and he was replaced by Nabil Bentaleb in the 54th minute.
Bayern was leading 1-0 at the time.
McKennie, who has six appearances for the United States, missed Schalke's defeat to Borussia Moenchengladbach last weekend after returning from international duty with a bruised knee from the Americans' 1-0 win over Mexico in a friendly.
McKennie has made 26 league appearances for Schalke.
