The Yankees placed McMahon on the 10-day injured list Wednesday with an ear/throat infection, Jack Curry of YES Network reports.
McMahon hadn't played since Sunday, and with the Yankees slated for a left-heavy upcoming schedule, the decision was made to IL the lefty-swinging McMahon. He is expected back from the IL when his 10 days are up. Jose Caballero, Amed Rosario and Oswaldo Cabrera could share the third base job while McMahon is out.
