"I committed to Iowa State on my official visit," said Jackson, who recorded 11 sacks as a sophomore in 2003. "I liked the coaching staff and the fact it's in the Big 12 Conference. I like how the team and the coaches were all pretty close. It was like a family atmosphere."
Jackson said his goal is to make an immediate impact in Ames this fall.
"I want to come in and play and contribute right away, being a guy that's coming from a junior college," he said. "I don't want to come in and sit on the bench. I want to help the team any way possible."
Jackson's commitment would raise the Cyclones' number of verbals to 25.
CN has also learned that Tearrius George is also still expected to sign a letter-of-intent with ISU on Signing Day, and that Manhattan, Kansas, will not be his destination.
