The New York Yankees placed first baseman Anthony Rizzo on the injured list Thursday with post-concussion syndrome linked to a collision with San Diego Padres star Fernando Tatis Jr. more than two months ago.

The incident with Tatis happened May 28 at Yankee Stadium. Rizzo collided with Tatis in a pickoff attempt. 

He injured his neck during the play, and he passed MLB’s concussion testing. But he has been in a bit of a slump.

Rizzo and Yankees manager Aaron Boone told the Yankees’ training staff the first baseman was feeling foggy. He underwent neurological testing that revealed the issue.

"Obviously, the struggles have been real documented, and in this game, you try to figure out what is going on whenever you’re struggling," Rizzo said before Thursday’s game against the Houston Astros.

"I guess now we can think two and two together, but over the last few weeks, you start going to the different checklists of mechanics, timing, consistently being late. Why am I consistently being late? I’ve made this adjustment plenty of times in my career. I didn’t forget how to all of a sudden do this."
