The 2016 recruit from North Gwinnett High in Suwanee, Ga., announced on Twitter that he would make a verbal commitment next week.
Imatorbhebhe, 6-foot-2 and 205 pounds, will choose among Alabama, Auburn, Florida, Georgia, Ohio State, Stanford and the Trojans.
Imatorbhebhe's brother, Daniel, is a freshman tight end at Florida.
USC offered a scholarship to Imatorbhebhe when he made an unofficial visit to campus in April.
"Humbled and very thankful to receive an offer," he wrote in a tweet, accompanied by a photo with receivers coach Tee Martin.
