Before concluding this past weekend's North Carolina official visit, Sean Martin committed to the Tar Heels. He announced the commitment on Monday evening.

Martin, a 6-foot-6, 260-pound defensive end from Bluefield (W.Va.), chose UNC over fellow favorites Penn State and West Virginia. He also was considering -- and had offers from -- Duke, NC State, Virginia, and Virginia Tech.

"After a great visit, prayers and a lot of thinking, I have decided to follow my heart and go where I feel best fits me as a person and player," Martin announced. "I am 100 percent committed to the University of North Carolina."

Back in March, Martin took his first visit to UNC; he attended the Heels' elite junior day, which was held in conjunction with the basketball game with Duke. He returned to Chapel Hill a month later for the spring game.

Assistant coaches Scott Boone and Tim Cross collaborated to recruit Martin.

Martin is the second defensive lineman to commit to UNC this week. Fellow D-end A.J. Beatty pledged to the Heels a week ago, also while on an official visit with the school. A total of 17 prospects have now pledged to UNC for the 2020 class.

For Bluefield High, Martin plays defensive end in a 4-4 defensive scheme. He finished his junior season with 144 tackles and 17 sacks.

According to the 247Sports Composite, Martin is a three-star prospect and the nation's No. 36 strong-side defensive end.
