The "Milk" star announced earlier in the week that he would not be speaking at the June 12 graduation ceremony due to a scheduling conflict with his next film.
Delson, a founding member of the multi-platinum rock act, graduated from UCLA in 1999 with a bachelor's degree in communications studies. In 2004, he founded the Delson Scholarship Fund, which gives yearly scholarships to students from Huntington Park, Calif.
"Brad Delson is not only an innovative musician, but he is also a social activist who is committed to change through education," Judith L. Smith, dean and vice provost for undergraduate education in the UCLA College of Letters and Science, said in a statement. "I am thrilled that Brad will be helping to commemorate this important occasion in the lives of our graduates and their families, and we are grateful that he has agreed to do so on short notice."
In the wake of the Franco news, some UCLA students had petitioned for new "Tonight Show" host Conan O'Brien to serve as speaker, but he reportedly turned down the request.
