CHICAGO (AP) — Hall of Fame second baseman Ryne Sandberg says the prostate cancer he thought had been eliminated by radiation has returned and spread.

The Chicago Cubs great made the announcement on Instagram on Tuesday.

Sandberg announced in January that he had metastatic prostate cancer and in August said he was cancer-free after chemotherapy and radiation treatments.

“Unfortunately, we recently learned the cancer has relapsed and it has spread to other organs,” he wrote Tuesday. “This means that I’m back to more intensive treatment. We will continue to be positive, strong, and fight to beat this. Thank you for your thoughts and prayers for me and my family.”

Sandberg was the National League MVP in 1984 and a 10-time All-Star during 15 seasons for the Cubs from 1982 to 1997, with 282 home runs and 344 stolen bases. After his playing career, he served as manager of the Philadelphia Phillies from 2013 to 2015, going 119-159.

The Cubs honored him this summer with a statue outside Wrigley Field.
