Yankees first baseman Anthony Rizzo will be placed on the 10-day injured list with post-concussion syndrome, the team announced Thursday.

When speaking to reporters ahead of a four-game series against the Astros at Yankee Stadium, manager Aaron Boone said the injury could possibly be traced back to May 28, when Rizzo collided with Padres outfielder Fernando Tatis Jr. while attempting to apply a pick-off tag.

“Just been complaining a little bit the last few days of some fogginess, so we ran him through a battery of tests, neurological stuff, and it kinda showed up and came back as some cognitive impairment,” Boone said. “So he’s gonna be shut down right now, and hopefully with the treatment he’s getting, we’ll start to see some improvements.”

After that game, Boone insisted Rizzo was “fine,” and even though he ended up missing the entire series against the Mariners that week, Rizzo also insisted that it “could’ve been worse.”

But after he returned, Rizzo started slumping.

Both he and Boone insisted the 33-year-old was healthy, and that there weren’t any lingering impacts from the Tatis collision.

Rizzo, after being one of the most consistent bats in the Yankees’ lineup through the early portion of the season, hit .173 in June and .167 in July, and during Sunday’s game against the Orioles, his season reached a new low point when he struck out in all five at-bats.

Boone said Thursday that Rizzo passed MLB’s testing in the days after the injury to “rule that stuff out,” but recently, he’d started to feel “foggy” — with Boone adding that it might’ve carried over to the plate, where Rizzo couldn’t connect on pitches he normally would.

Rizzo didn’t play in Wednesday’s series finale against the Rays, though he did play in the first two games and recorded a hit each night.

In a corresponding move, the Yankees recalled outfielder Oswaldo Cabrera from Triple-A Scranton/Wilkes-Barre.
