Solomon, who also has an offer from Illinois, says he is thrilled to have the Boilers on board.
"I was very excited to have another offer come through. It's very amazing to have another offer under my belt. I am honored to have my second offer come from Purdue."
Solomon visited West Lafayette during the season and likes what he has seen of the program.
"Purdue has great tradition as well as a great coaching staff and great academics."
Purdue also offered his junior teammate and bookend tackle Matt McCann.
