Giants broadcaster Duane Kuiper announced Monday that he “may be missing a few more Giants broadcasts than usual” after a diagnosis that will require the broadcasting veteran to begin chemotherapy treatments.

Kuiper, who will be 71 later this month, did not announce a specific medical diagnosis, but in a statement released through the club on Monday, he explained that upcoming absences on Giants broadcasts would be related to his health condition.

“I feel very fortunate that I have an incredibly talented team of doctors and healthcare specialists who will be assisting me through my treatment plan,” Kuiper said in a statement. “And of course, the support and love of my entire family, along with our incredible fans, everyone at the Giants, NBC Sports Bay Area and KNBR is overwhelmingly and deeply appreciated.”

Kuiper began broadcasting Giants games immediately following the end of his playing career in 1986 and worked in San Francisco’s organization through 1992. After spending the 1993 season in the Colorado Rockies’ booth, Kuiper returned to the Giants and has been one of the most celebrated voices in baseball ever since.

Kuiper’s chemistry with Giants color commentator Mike Krukow is one of the signature elements of team broadcasts as the duo have worked together for more than three decades. Their run is one of the longest of any pair in MLB broadcasting history and both have indicated in recent years they would like to continue broadcasting Giants games as long as it remains feasible to do so.

“I still plan on broadcasting this season, though I may take a few more games off if I’m not feeling well and I want to thank my broadcasting partners for their unconditional support and willingness to step in and cover for me.”

Including Kuiper, the Giants have three rotating play-by-play voices including Hall of Famer Jon Miller and Dave Flemming. Aside from Krukow, the Giants have featured a handful of different former players as color commentators on broadcasts this season including Randy Winn, Shawn Estes and Javier Lopez.

“The entire Giants Family sends our love and support to Duane and his family during this challenging time,” the organization said in a statement. “We know we speak for Giants fans everywhere in offering our prayers for a safe, speedy and full recovery.”
