Detroit Lions rookie linebacker Caleb Campbell, a West Point cadet who is taking advantage of new military rules allowing cadets with special talents to avoid active-duty military service, will be permitted to take part in the Lions’ minicamp this week.

Campbell was initially expected to miss the camp because of the NFL rule limiting first-year players to one minicamp before the conclusion of their schools’ academic year. But Mike O’Hara of the Detroit News reports that Campbell, who is scheduled to graduate from West Point on May 31, has rescheduled his final exams to get them all done early.

Therefore, the NFL will have considered Campbell to have completed his academic year — a strange ruling that seems at odds with the way the NFL is treating players like former Delaware quarterback Joe Flacco, who can’t practice with the Ravens until Delaware finishes its semester, even though Flacco himself is no longer enrolled in school.

A seventh-round draft pick, Campbell will be allowed to play pro football this year while spending some time helping with the military’s recruiting efforts if he makes the Lions’ or some other team’s roster. If he doesn’t make an NFL roster, he’ll serve on active duty.
