The 24-year-old rookie was signing autographs down the right-field line when he was hit on the back right side of his head. According to a person who witnessed the incident, Montgomery appeared to be "woozy" but remained conscious.

According to the YES Network's Meredith Marakovits, the liner that struck Montgomery was hit by Sandy Leon of the Red Sox.

Montgomery was recalled from Triple-A Scranton/Wilkes-Barre on Friday to start Sunday's game in place of left-hander CC Sabathia, who sustained a right knee injury during his last start at Toronto. In 21 starts for New York, Montgomery has gone 7-6 with a 4.05 ERA.
