Chicago White Sox first baseman Jose Abreu and Kansas City Royals third baseman Hunter Dozier both left Game 1 of Friday's doubleheader after they collided in the second inning.
Dozier, who left with a quad contusion and neck discomfort, was placed on the seven-day concussion injured list, and the club recalled Kelvin Gutierrez from Triple-A Omaha prior to Game 2 of the doubleheader.
Abreu is day-to-day after leaving the game with a facial contusion, laceration and bruised left knee. The initial assessment for a concussion was negative.
"He's doing well enough that he wants to play the second game [of the doubleheader]," White Sox manager Tony La Russa said.
