Jansen will not be available to pitch Saturday against the Mets, Fabian Ardaya of The Athletic reports.
Although Jansen threw just 19 pitches Friday, he did complete two high-leverage innings, leading manager Dave Roberts to give him a day off Saturday. With Blake Treinen, Brusdar Graterol and Justin Bruihl also resting, the Dodgers will have to look elsewhere for late-innings relief work.
