Harvey was in Ames over the weekend for an official visit with his mother and wanted to return to Florida to talk things over with his father before deciding to commit to Iowa State on Monday afternoon. Harvey committed to Southern Miss two weeks ago, a week after Iowa State offered.
The 6-foot-1, 215-pound Harvey also had offers from Marshall, Western Kentucky and Western Michigan and could play either Mike or Will linebacker in college — depending on how much weight he adds.
Harvey's commitment brings the Cyclones to 25 verbals for the 2014 recruiting class with National Signing Day on Wednesday.
Counting Sam Seonbuchner and Reggan Northrup, ISU will sign three high school linebackers.
