The End Zone Complex was completed and dedicated in 2002. The facility located in the south end zone of UFCU Stadium houses the athletic program's football operations. The End Zone Complex also has a full service training center, meeting rooms and coaching staff offices. The capacity grew to over 16,000 at the beginning of the 2009 football season with the completion of the first phase of a multi-phased expansion. This first phase added The Jerry and Linda Fields West Side Complex, a three-tier structure (by adding onto the existing home side) that includes new premium club seating, with 450 seats, and 15 luxury suites. The facility's funding came from a donation by Texas State
alumns Jerry and Linda Fields. In 2012, a $33 million expansion closing in the north end zone brought the stadium's capacity to 30,003. That season, the average attendance was 18,945 in the program's first season as a Division I FBS member. In 2024, chair back seats were added to the east side, reducing capacity to 27,149. The opening of the new south endzone club and seating, in 2025, brought the capacity back to 28,388 In May 2024,
University Federal Credit Union (UFCU) paid $23 million for the naming rights to the stadium for 15 years. ==Other uses==
