Umpire Ron Kulpa, aged 57, has been diagnosed with a concussion after a foul ball struck his mask during the fourth inning of the game between the Miami Marlins and New York Yankees. The incident occurred on the first pitch from Paul Blackburn to Jakob Marsee, with Kulpa initially remaining in the game after speaking with catcher Austin Wells. However, he later stepped away from the plate and was checked by athletic trainers before exiting under his own power. Kulpa will be sidelined for at least a week while undergoing follow-up exams and care according to Major League Baseball (MLB) concussion protocols. Scott Barry, who was umpiring at first base, took over Kulpa's duties behind the plate for the remainder of the game, which resumed after an 11-minute delay. Kulpa has been a part of the major league staff since 1999 and has officiated in the World Series in 2011 and 2021.
