Dodgers manager Dave Roberts said after Wednesday's 14-1 win over the Reds that Ohtani (knee/biceps) will be placed on the 15-day injured list, Fabian Ardaya of The Athletic reports.

Ohtani returned to the lineup Monday following a four-game absence, but he felt more discomfort this week and will now be forced to the shelf due to his nagging knee and biceps injuries. As a two-way player, he will have to be placed on the 15-day IL as opposed to the 10-day IL, per MLB rules. The Dodgers will bring up top prospect Josue De Paula to take on the lion's share of the reps at designated hitter while Ohtani is out.
