Detroit Tigers prospect Riley Greene has been scratched from the Arizona Fall League roster.
The 21-year-old center fielder sustained a concussion during his final game for Triple-A Toledo, an Oct. 2 matchup against the St. Paul Saints at Fifth Third Field in Toledo, a source with knowledge of the situation told the Free Press on Monday.
Trying to make a play with two outs in the fourth inning, Greene lost sight of a fly ball but attempted to recover with a diving catch in left-center field. As Greene extended his body, he collided with left fielder Jacob Robson.
