Reds center fielder Ryan Freel had feeling in all of his extremities and was coherent after colliding with right fielder Norris Hopper on Monday.
Freel, known for his all-out play, was down for 13 minutes while being examined and was taken off the field on stretcher.
The frightening scene took place in the third inning of a game against the Pittsburgh Pirates. Freel and Hopper chased a ball hit by Humberto Cota leading off the inning. Freel caught the ball on the warning track and his left arm was run into by Hopper. Freel was twirled around to his left and fell at the base of the wall.
After being examined by Reds trainers and physicians, Freel was turned over on his back, strapped to a stretcher, loaded into an ambulance and taken to Good Samaritan Hospital.
The Reds announced Freel's condition in the fourth inning. He was scheduled for further exams.
Hopper remained in the game.
Freel, hitting .253 entering the game, was replaced by Ken Griffey Jr.
