"Buffalo has offered me," said Rigg. "I received a message from their tight ends coach (Marty Spieler) to contact him and when I did he said I had an offer."
The 6-foot-5, 245-pound Rigg is now in the process of learning more about the Bulls and looking for a possible visit.
"I'm hoping to get up there soon for a visit and learn more about their program," said Rigg. "I've heard good things about them and Coach Spieler said they are in need for a tight end. So I'm hoping to visit them in the next couple of weeks."
With offers from Ball State and Ohio University, Rigg should continue seeing more interest as he gets closer to his senior season.
