Chicago White Sox reliever Joe Kelly exited Thursday's game against the Royals due to lightheadedness.
The veteran entered the contest to begin the seventh inning. He faced three batters and recorded just one out before heading to the dugout with a trainer.
This is just the latest mark on a long list of ailments for Joe Kelly. He most recently exited a game on July 27 due to biceps discomfort. The right-hander also suffered a hamstring injury in June after beginning the year on the IL.
