New York, NY (My Sportsbook) - Pathology reports have revealed that the tumor removed from the brain of former New York Yankees star Bobby Murcer was malignant.

"As we begin a new year, I find myself facing a new challenge -- the biggest of my life so far," said Murcer in a release from the Yankees. "Pathology reports have revealed that the brain tumor removed was malignant. I'm not having to battle this alone, but am fortified with the most loving family, an abundance of wonderful friends and fans and the very best class of physicians."

The 60-year old Murcer, who had been suffering from headaches and a loss of energy, underwent surgery shortly after Christmas to remove the tumor. According to the New York Daily News, though, the surgery was unable to contain other invasive cancer cells, despite completely removing the tumor.

"I'm gaining confidence that with God and my faith leading the way, we will as a team put up an incredible fight. Please continue to send up prayers," Murcer added. "That's all I can really ask of you at this time."

An MRI on Christmas Eve discovered the tumor and Murcer then decided to seek treatment at the MD Anderson Hospital in Houston, one of the top cancer facilities in the country.

Murcer, who is scheduled to undergo six weeks of extensive chemotherapy and radiation, has been a Yankee broadcaster since he retired as a player in 1983. His relationship with the Yankees, though, dates back to 1965.

"Bobby Murcer represents the spirit of the Yankees, and above all, he's my dear friend," said Yankees owner George Steinbrenner. "I know Bobby very well. He has true grit, is a fighter and our entire Yankee organization offers our prayers to him and his family for a big win in this battle."

In 17 seasons in the majors, all but four of which were not spent in pinstripes, Murcer hit .277 with 252 home runs and 1,043 RBI. He played in San Francisco from 1975-76 before playing two seasons with the Chicago Cubs, who eventually traded him back to New York in 1979.
