“I've been close friends with Paul Westphal ever since his 1972-73 rookie year with the Boston Celtics and had the pleasure of celebrating his wonderful career with him last September when he was inducted into the Naismith Memorial Basketball Hall of Fame,” Lupica wrote. “With his permission I am letting the basketball world know he has just been diagnosed with brain cancer. Specifically glioblastoma. Please pray for friend, No. 44.”

Westphal, 69, was a five-time All-Star, four-time All-NBA member and a member of the 1973-1974 champion Celtics team.
