TBI is a commonly seen initialism in US reporting that stands for “Traumatic Brain Injury”. Given the relative amount of education in Tennessee, and their backwards stance on every issue from women’s health to wearing mixed fabrics, identifying as the ‘TBI’ is er… rather unflattering.
A reasonable policy. Would that more people were of the same inclination, then maybe there would be less cause to use “TBI” with such frequency in sports reporting
