Jordan Montgomery struck in head during batting practice prior to Saturday's game

Yankees rookie starter Jordan Montgomery was struck in the head by a wayward foul ball during pregame batting practice while signing autographs.

Montgomery was recalled from Triple-A 24 hours ago to replace the injured CC Sabathia, who was placed on the 10-day disabled list with right knee inflammation.

The Yankees rotation has dealt with numerous injuries of late, as Masahiro Tanaka landed on the 10-day disabled list on Saturday with right shoulder inflammation.

Montgomery leads all rookie pitchers in strikeouts with 111, and was in line to toe the rubber for Sunday's series finale against Red Sox ace Chris Sale.

In 21 starts this season, Montgomery has gone 7-6 with a 4.05 ERA, and 111 strikeouts versus 35 walks.
