Tuesday morning, the Sporting News reported that Hall of Fame catcher Gary Carter’s brain tumors may be inoperable, according to his daughter:

Kimmy Bloemers, the daughter of baseball Hall of Famer Gary Carter, wrote on the family’s website that her father’s brain tumors are inoperable, the Montreal Gazette reports.

“Dad’s tumor is not operable, as it is like a snake of tumors that are connected across the back of the brain,” Bloemers wrote. “The biggest tumor is on the left side of the brain.”

Carter was diagnosed with brain tumors about 10 days ago, after an MRI in West Palm Beach, Florida. The article goes on to say that the tumors are probably “Grade 4 glioblastoma” and that the Hall of Famer’s doctors would continue to try to fight to shrink the tumors by any means possible.

Carter hit .262 with 324 homers and 1225 RBIs over a 19-year major league career spent mostly with the Montreal Expos and New York Mets. He was inducted into baseball’s Hall of Fame in 2003.
