The 6-foot-4, 265-pound Dorsey, who plays defensive tackle for the Crimsons, landed his first offer from Navy and then made a call on Wednesday morning to the U of L coaches.
"Coach (Chris Klenakis) said they had gone over my film and they liked me a lot," Dorsey said. "So, he said they wanted to offer me. It was really nice.
"It's a real blessing for me, especially with a school like Louisville."
Dorsey said he's also been hearing from Kentucky, Western Kentucky and Miami of Ohio and said he made an unofficial visit to Notre Dame and will camp there this summer.
"Coaches say they like how I always hustle and give 100 percent," Dorsey said. "They say they like me because I really care about the game."
Dorsey grew up in Louisville but said he's always been a "neutral" fan because he has a lot of family in Lexington that are big UK fans.
"I've always been a Louisville supporter," he said. "I went to (Junior Day at U of L last week) and really liked it a lot. I got to talk to a lot of the coaches and meet them. I spoke for a while with the defensive line coach (L.D. Scott) and liked it.
"I really like what they are doing over there."
