Willy Garcia was temporarily knocked unconscious after he was struck by his Chicago White Sox teammate Yoan Moncada's knee in the sixth inning Monday against the Toronto Blue Jays.

As both players chased down Darwin Barney's bases-loaded fly ball, Moncada's knee careened into the head of Garcia, who somehow still managed to catch the ball in his glove before it popped out a second later, thereby ruling the catch void. Garcia, though, couldn't assert whether it was or it wasn't, as he didn't remember colliding with his teammate at all until he saw a replay of the event, he told MLB.com's Scott Merkin.

"When I saw the video, I saw the collision, I was like, 'Wow, that was hard," he said, according to Merkin.

Following the scary incident, the White Sox announced Garcia was diagnosed with a head contusion and would be evaluated further Tuesday.

Moncada, meanwhile, was diagnosed with a knee contusion and is listed as day to day.
