MARQUETTE, MI -- A Northern Michigan University sophomore suffered a medical emergency and died Tuesday following a morning workout with his football teammates.

Attempts by emergency crews to resuscitate 20-year-old Anthony Herbert were unsuccessful, according to an NMU spokesperson.

"What caused his passing is unknown at this time and right now our concern is for Anthony's family, friends, teammates, coaches and team staff, teachers and fellow students," said University President Fritz Erickson in a statement.

Herbert participated in an early morning workout Tuesday, Jan. 17 and went to breakfast before returning to his room in Spaulding Hall. There, EMTs were called to his aid after he suffered a medical emergency, officials said.

Soon after the incident, counselors were on site to support Herbert's friends and teammates. They'll continue to provide services to those impacted who need help dealing with the loss.

"We will be talking with Anthony's family on their wishes regarding memorial/funeral services and will keep the campus informed as those details become available," Erickson said in a statement."

Herbert, a 6-foot-4, 315-pound right guard, started in all 11 games during the 2016-17 season. The construction management major was later named to the all-GLIAC academic team.

"In my brief time with Anthony, I could tell that he was a great young man," said head football coach Kyle Nystrom in a statement. "He was well-respected by his coaches and teammates and was a leader on the offensive line. We are devastated by this tragedy, and we are keeping his family in our prayers."

As news of his death spread around campus and back to his hometown of Lapeer, Herbert's friends took to social media to share their disbelief.
