"It has been an incredible run and after discussing things with my family, I have decided to declare for the 2018 NFL Draft. The relationships I have built, and the experiences I have had are absolutely priceless," said Sutton.
A junior, Sutton racked up over 1,000 yards in each of his past two seasons. He hauled in a total of 31 touchdowns over the past three years, catching a total of 193 balls over that time.
Sutton received a medical redshirt in 2014, after catching two passes for 27 yards in just two games.
He finishes third on SMU's all-time receiving list behind Denver Broncos receiver Emmanuel Sanders and Aldrick Robinson of the San Francisco 49ers.
