MLB Star Jose Abreu Injured After Violent Collision With Royals Player On Field

Scary scene on the Chicago White Sox's diamond Friday ... reigning AL MVP Jose Abreu and Royals star Hunter Dozier were injured after colliding at full speed on the field.

The play happened in the second inning of the first leg of the Sox's doubleheader with Kansas City ... when Dozier hit a pop-up just feet from home plate.

As the Royals 3rd baseman, though, put his head down to run to first ... Abreu came sprinting in with his eyes toward the baseball in the sky.

The two then crashed into each other ... knocking heads and shoulders -- before crumpling to the ground.

You can see in the slow-mo footage from the dugout ... the collision was VIOLENT -- and the two laid on the infield in pain for several minutes.

Both players were eventually helped off the field and forced from the game. It's unclear if they've suffered any significant injuries from the collision.
