Umpire Larry Vanover is being evaluated for a concussion and other injuries at a hospital after being struck in the head with a relay throw during Wednesday’s game between the New York Yankees and Cleveland Guardians.

The 67-year-old Vanover was knocked down by the throw from Guardians All-Star second baseman Andrés Giménez, who wheeled and fired toward the plate and hit Vanover, positioned on the infield grass between second and the mound, on the left side of his head.

Major League Baseball said Vanover said is being checked for a head injury “and other potential medical issues. The timeline on his return is to be determined.”

Plate umpire Chris Guccione told a pool reporter Vanover had “a pretty good-sized knot” on his head. He’s been taken to Cleveland Clinic.

“They’re going to do a concussion test and it sounded like he was coherent and that he knew kind of what was going on,” Guccione said. “But he did have that glazed look on him. He’s going to be at the hospital for the rest of the night maybe.

“That was scary. Very hard to focus after that after you see a colleague get hit. But they gave me updates, and I was like, ‘All right. He’s good. He’s in safe hands.’ So, we moved on.”

Vanover, who had ejected Yankees manager Aaron Boone in the first inning following a controversial play, was knocked off his feet by the throw. His hat flew from his head as he tumbled to the turf.

Giménez was visibly upset and many in the matiness crowd of 23,164 at Progressive Field gasped when Vanover was hit.

Vanover got to his feet without assistance and was checked by Cleveland’s trainer before being escorted off the field. Vanover has 29 years of major league umpiring experience.

The game continued with a three-ump crew.
