Manager Dave Roberts stated that Ryu will require a trip to the injured list after straining his groin during Monday's start against the Cardinals, Pedro Moura of The Athletic reports.
The Dodgers are unsure as to how long Ryu will remain on the injured list, but he certainly won't be making his next scheduled start. With Rich Hill (knee) and Clayton Kershaw (shoulder) already on the 10-day IL, it's possible the Dodgers turn to pitching prospect Dennis Santana to make a spot start, as he is already working as a long reliever out of the big-league bullpen.
