If it is graduatel program, you will meet them(TAMU faculty) in the conferences and other places.  They will remember your name and they will tell your professor about the story.  Usually, one of the admission faculty members will check your references and ask them whether they remember this student and what was the overall impression.  If it's undergrad, you don't need to worry about it.  They will kick you out if you submitted some ill information.  Even it's the last minutes. Did you tell thme about other schools that you applied?  Then, they will inform them for sure.
