Normally a defensive lineman, Jefferson played tight end in the event and looked good doing it.
"San Diego State offered me last week," said Jefferson. "Coach (Jeff) Horton offered. They like me as a defensive tackle."
A number of other schools are interested in the three-star.
Jefferson said that he's open to any position on the defensive line but has his preferences.
"I can play 3-tech or 4-tech, be a defensive end in a 4-3," said Jefferson. "But really I just want to play on the defensive line."
Arizona and Arizona State are expected this week and UCLA and USC are scheduled to come by next week.
Jefferson plans to camp at the Oakland NFTC and the UCLA Camp in June.
