Texas A&M has sued the Indianapolis Colts for infringing on their trademark of the "12th Man."
At a board of regents meeting Thursday, school chancellor John Sharp revealed that Texas A&M filed suit in district court in Houston on Thursday after it says repeated attempts to stop the Colts from using its registered trademarks were unsuccessful.
The suit alleges that the school first contacted the Colts about using the phrase inside its stadium in 2006 and sent a cease and desist letter, which it says fell on deaf ears.
