Longtime San Francisco Giants broadcaster Duane Kuiper is stepping away from the booth temporarily to undergo chemotherapy.

In a statement issued through the Giants, Kuiper announced Monday that he has been diagnosed with an unspecified medical condition that requires chemotherapy treatment. Kuiper said he intends to broadcast again in the 2021 season, although he cautioned that he might need to take some extra games off if he is not feeling well enough.

NBC Sports Bay Area pledged “complete and unconditional support” to Kuiper as he deals with his health issues.
