Running back Johnathan Franklin, a fourth-round draft pick of the Green Bay Packers, has to miss all of the team’s remaining offseason work except this weekend’s mandatory minicamp because of the NFL’s graduation-related rules.

But his teammate at UCLA, defensive lineman Datone Jones, can participate in all offseason work because he graduated last year. Jones was the Packers’ first-round draft pick.

According to NFL rules, rookies can’t take part in their new team’s offseason practices, except for their rookie minicamp, until after their schools’ final exams in the spring or summer. It doesn’t matter whether the player is or isn’t enrolled in school, unless he’s in graduate school, in which case he’s not subject to the restrictions.

UCLA is one of the relatively few schools on the quarters system, and according to its website, its exams end Friday, June 14. The Packers’ offseason OTA practices begin next week and finish the week of June 14, so Franklin will have to miss all 10 of those practices plus the full-squad, mandatory minicamp held June 4-6.
