Tega was a mischievous girl growing up in Lagos, Nigeria, and was often in trouble with her parents for misbehaving. Her punishment was to sit quietly in time out beside her dad, who would often watch boxing—a punishment she soon came to enjoy. Before long, Tega fell in love with the sport, and later soccer and tennis. After completing university, she became a sports journalist and soccer pundit where she has covered live broadcasts of the English Premier League, UEFA Champions League, and Africa Cup of Nations. Tega served as one of a small number of female pioneers in Nigerian sports journalism, joining the International Sports Press Association and serving as secretary of the Events Committee of the Sports Writers Association of Nigeria.

Currently a sports producer and presenter for Smooth 98.1 FM Radio, Tega is also the founder of the Ladies in Sports Conference, a yearly conference networking female sports professionals in Nigeria. The conference has grown to include more than 120 participants, including registrants from Kenya, Ethiopia and Zambia, and has gained international recognition by forming partnerships with La Liga in Spain and Women in Football in the United Kingdom.
