Nebraska freshman wide receiver Keyshawn Johnson Jr., the son of all-time great Keyshawn Johnson, is taking a leave of absence from the program. Johnson Sr., along with Cornhuskers coach Mike Riley, confirmed the receiver's departure to Sam McKewon of the Omaha World-Herald.

The elder Johnson said he wanted his son to "mature" during his time away from the team. "You're in college now," Johnson told the paper. "You're an adult. You're not a kid. You take a look at it from afar and let me know how important it is to you."

Johnson Jr. posted the following, succinct message on Twitter on Tuesday.

Earlier this month, Johnson Jr. was cited for marijuana possession and possession of drug paraphernalia in a dorm room. He enrolled early in January to get a head start on practice, but an illness set him back heading into spring practices.

"One thing you will not do as my son is you will not embarrass Nebraska, you will not embarrass Mike Riley and you will not embarrass this family," Johnson Sr. said. "If you mature and you're ready to resume your football career and academic goals, then Nebraska will be ready to embrace you."
