Terrance Gore suffered a broken jaw after getting hit by a pitch in a minor-league game on Friday, Royals manager Ned Yost relayed.
"I just heard about it," Yost said. "Doctor said it wasn’t the worst break you can have, but it was a fractured jaw."
The team optioned Gore to Class-A Wilmington last week and shifted him to minor-league camp.
Gore reached the major leagues as a pinch-runner last September. He is the fastest player in the organization, and many scouts view him as the fastest man in all of baseball.

But he is still developing the other facets of his game. Gore posted a .542 on-base plus slugging percentage with Wilmington last season.
Now that development will be delayed by his injury.
