Nelson, who is 6-foot-5, 280 pounds, received an offer from Tennessee on Tuesday as his total climbs toward 30.
"I called coach (Don) Mahoney, the offensive line coach, and he offered me," Nelson said. "He told me they were going to be losing four linemen next year because they're seniors, and they might even lose their left tackle, who's a junior, because he might go to the pros."
Nelson doesn't know much about the Vols, but he is excited to see the campus. He plans on visiting Vanderbilt in the late spring or early summer, and is working in a trip to Knoxville, Tenn., as well.
"(Mahoney) said he really likes me and he would love for me to come visit," Nelson said. "I've seen a picture of the campus and the weight room, and it's beautiful. I think when I go out to see Vanderbilt, I'll probably swing by and see Tennessee."
