Diago Gonzalez, a junior, was airlifted to an Austin hospital after he collapsed after making a tackle in an Oct. 10 game at Yoakum.
Goliad's T-shirts & More by Liz created the "Diago Strong" T-shirts to help raise money for Gonzalez's medical expenses. The T-shirts cost $15 with $10 from each sale going to the family.
Students and faculty at all four campuses participated in "Diago Day" on Thursday.
Gonzalez is recovering in an Austin rehabilitation facility.
