MIAMI -- St. Louis Cardinals right-hander Kyle Gibson was scratched from his scheduled start just before Wednesday's game with the Miami Marlins because of back tightness.

Gibson (5-2, 3.44 ERA) had been away from the team this week on bereavement leave after a death in his family. About two hours before the game, Cardinals manager Oliver Marmol said Gibson had gotten in his normal workouts during his absence and had expected no issues.

Gibson was replaced by Matthew Liberatore, who gave up homers to the Marlins' first two hitters, Bryan De La Cruz and Jesus Sanchez.
