Herron, who was an early 2012 commitment for Charlie Strong's Cardinals, received a visit from IU head coach Kevin Wilson last week and the Hoosiers offered the Avon, IN., standout a scholarship on Monday.
That news forced the 6'6, 330-pound Herron to do some soul searching about his future. After discussing his options with his family, Herron decided to stick with his commitment with Louisville.
"I'm going to sign with Louisville tomorrow, for a fact," Herron said Tuesday. "IU plays in the Big 10 against Ohio State, but I didn't want to get my (butt) kicked all four years, especially with Urban Meyer there, plus Michigan is really good. So I wanted to open a new door and take my talents to the Big East. Louisville was my first choice and I think it's going to be a good fit and a good choice. My mom said not to second guess my first choice."
Herron admitted he considered the Hoosiers late scholarship offer.
"It hit us pretty hard yesterday when we heard about IU's offer," Herron admitted. "But we were like, 'why they wait till signing day?' We took the pros and cons, but I decided to stay with Louisville."
With Herron in the fold, the Cardinals will have some recruiting help with his high school teammate Elijah Daniel, a talented 2013 defensive line prospect who recently received an offer from UofL.
"I tell him everyday about Louisville," Herron said. "He wants to come down to one of the spring games when I go so I'll bring him."
Herron now awaits the results of his latest attempt on the SAT. Herron re-took the test for the fourth time last Saturday and should know his result by mid-February.
"It went alright," Herron said. "I feel like I did pretty good on it."
Herron said he will sign with Louisville Wednesday morning at 8:30 a.m. during a ceremony at his school.
