http://www.statutes.legis.state.tx.us/D ... htm#46.035(b) A license holder commits an offense if the license holder intentionally, knowingly, or recklessly carries a handgun under the authority of Subchapter H, Chapter 411, Government Code, regardless of whether the handgun is concealed or carried in a shoulder or belt holster, on or about the license holder's person:
...
(2) on the premises where a high school, collegiate, or professional sporting event or interscholastic event is taking place, unless the license holder is a participant in the event and a handgun is used in the event;
...
(l) Subsection (b)(2) does not apply on the premises where a collegiate sporting event is taking place if the actor was not given effective notice under Section 30.06.
