Witucki was born in South Bend, Indiana and attended Washington High School. While there, he played high school football as a guard on teams that went 14-1-4 in 1944 and 1945. He was awarded All-State honors and was chosen captain in 1945.[1]
Witucki attended and played college football at Indiana University in Bloomington. He was a four-year letterman and graduated in 1950.
Witucki was drafted in the 21st round (266th overall) of the 1950 NFL draft by the Washington Redskins. He played for the Redskins in 1950 and 1951, and after military service, from 1953 to 1956.
Witucki missed the 1952 NFL season because he was called to duty in the United States Air Force during the Korean War. He was awarded the rank of second lieutenant and was stationed in Japan. While he was stationed at Ashiya Air Field, he played football for the Ashiya Mustangs.[2]
