St. Louis Cardinals shortstop Edmundo Sosa hit first base umpire Junior Valentine in the face with an errant throw during the second inning of Monday's game against the New York Mets.
Valentine stayed in the contest despite the injury.
Crew chief Jerry Meals said Valentine didn't break any bones in his face.
"He was incredibly alert from the get-go. The blood seemed to stop fairly quickly ... and he was adamant that he was fine," Meals said postgame, according to Anthony DiComo of MLB.com.
