Lubratovich signed with the Brooklyn Dodgers in August 1931 and immediately won a spot as a starter at the tackle position. The Brooklyn Daily Times wrote: "Perhaps the outstanding addition is that of Milo Lubratovich, The University of Wisconsin's great tackle. Weighing 230 pounds, he was fast and powerful, and his ability to get under a kick was uncanny."[6] He played at the tackle position, both on offense and defense, for the Dodgers from 1931 to 1935. He appeared in 53 NFL games, 50 of them as a starter.[2][7]
Lubratovich served in the army in World War II. He later worked as an engineer for a concrete restoration company.[8] He was inducted in 2008 into the University of Wisconsin Athletic Hall of Fame.[9]
