In late February 2008, an MRI scan led Murcer's doctors to perform a biopsy, and, optimistically, the biopsy revealed scar tissue, rather than a recurrence of brain cancer. Murcer stated he planned to rest until spring training where he planned to call Yankee games and work in the YES Network studio. He released his autobiography "Yankee For Life", co-authored with Glen Waggoner, on May 20; he appeared in the broadcast booth for the last time two weeks earlier to promote it. The book dealt with his forty years in Major League Baseball and his battle with brain cancer. His last public appearance was May 27, in New York while promoting his book, signing autographs for 2,000 fans despite being frail and physically weak. In addition, he had planned to work 60 Yankee home games for the 2008 season.
