San Diego Padres star Luis Arraez has been placed on the 7-day injured list and entered into the concussion protocol after a scary moment during Sunday night's game against the Houston Astros, the team announced Monday.

Arraez ran directly into Astros second baseman Mauricio Dubón while trying to make it to first after a sacrifice bunt in the first inning of the matchup at Daikin Park. Arraez and Dubón collided hard and both immediately fell to the ground, though Dubón jumped back up quickly.

Dubón’s shoulder appeared to make contact with the head of Arraez, who was motionless on the field as trainers rushed to his aid.
