Despite the action, Johnson camped at Iowa two days later. He had planned it months in advance.
"Right now, I'm still committed to Ball State," Johnson said. "I'm a a strong commit to Ball State right now. They're my only offer. They only have 15 scholarships so I took mine."
Schools like Iowa, Indiana and Purdue continue to recruit Johnson. He is not closing the door on them.
Hawkeyes assistant Eric Johnson visited Lafayette Jefferson High during the spring open period, Matthew Johnson said.
"I talked to him and told him that I would be at camp," Matthew said. "At that point, he was just trying to get to know me and see how I was doing in school. He said they wanted to get a look at me at receiver and (defensive back) in camp."
The Iowa staff mostly watched Johnson work out at cornerback last week.
"I ran a good 40 time," he said. "They said that I did really well with the drills. They said that they all liked me and that I had a good character about myself."
Johnson couldn't remember his 40 time but based on his spring track season it likely was strong. He won an Indiana State championships in the 100 (10.74 seconds with crosswind) and 4x100 earlier this month. He ran the 100 in 10.61 at sectionals.
"(The Iowa coaches) said they were very impressed because that was my first time playing corner as much as I had this year," Johnson said. "They said I had really good hips."
Johnson (5-11, 175) mainly has served as his school's quarterback, only taking a few reps on defense and receiver in his career. Other than Eastern Michigan, he's been recruited as a defensive back, though, he said.
Johnson is expected to start at cornerback and quarterback this year. Colleges are going to scout his early season on defense.
"I feel like that's what everyone is waiting on," Johnson said. "I've been told by most schools that they're going to wait and watch my first three games at corner and see how I do. Purdue and Indiana said that they're both close to offering. They just want to see my first three games at corner."
Johnson said Iowa has told him the same thing.
"I camped at all these schools this summer to get some work at corner so I can learn more technique and be able to use that when I play this year," he said.
