St. Louis Cardinals rookie Stephen Piscotty has been diagnosed with a "head contusion" after being involved in a sickening outfield collision with team-mate Peter Bourjos.
The incident, which took place during Monday night's game against the Pittsburgh Pirates, occurred when Piscotty and Bourjos both chased after a flyball that was hit towards the deep left-center outfield by Pittsburgh's Josh Harrison.
Piscotty was unsure whether Bourjos was going to get to the ball and subsequently dove to take the catch. Bourjos did end up taking a sliding catch, but caught Piscotty with a left knee to the head in the process.
Bourjos and Cardinals right fielder Jason Heyward immediately called for medical assistance as it appeared that Piscotty had been knocked unconscious. By the time he was stretchered out of PNC Park, Piscotty had regained consciousness and was anle to wave to the fans.
The Cardinals later confirmed that Piscotty had suffered a head injury and would remain in hospital overnight for further observation.
The Cardinals went on to win the game 3-0, with all three runs coming in the ninth innings.
