"I hit a bunch of camps, plus I've been working out with my team five days a week," he said. "We've been preparing hard during the summer getting ready for this year. I've improved over the summer because of all the camps that I went too."
Petersen, who participated in camps at Alabama, Arkansas, Baylor, Oklahoma State and Tennessee over the summer months, has also made three unofficial visits to visit with coaches, tour facilities and learn more about the schools.
During his time in the Derby City, Petersen was able to see U of L's top-flight facilities first-hand and meet with members of the Cardinals coaching staff.
"It went about as good as I could expect," he said of his U of L visit. "It blew my mind. I came out of the visit with an offer."
Louisville joins North Texas and Tulane as programs that have extended a scholarship offer to date. Others programs, such as Arkansas and Oklahoma State continue to evaluate the lineman.
"I'm not a pick a favorite kind of guy, so I'm trying to keep my options open right now," Petersen said. "I don't have any type of timeline to make my decision or anything."
Instead of being concerned about the timing of his college decision, Petersen is making plans to learn even more about the school's that have shown high interest in him.
"Arkansas and Oklahoma State want me to come up for an unofficial visit for a game, plus they said that they'll be coming to a couple of my games," he explained. "I also plan scheduling official visits with Louisville, North Texas, Tulane and probably Arkansas."
