The reasoning is because he hasn't graduated and the final exams at UCLA don't conclude until June 14.
NFL rules, as published by Sando, are as follows:
- Players who participated in college football in the 2012 season as graduate students, or who have already graduated or who will graduate prior to May 13, may not participate in any activities other than the three-day minicamp until May 13;
- If final examinations at a player's school conclude prior to May 13, the player may not participate in any activities other than the three-day minicamp until May 13, even if the player has left or leaves school;
- If final examinations at a player's school conclude after May 13, the player may not participate in any activities other than the three-day minicamp until after the player's final day of examinations. If the player has left or leaves school, he may not participate in any activities until after the final day of examinations at his school. These restrictions do not apply to a graduate student, who is permitted to report to his club and participate fully in a Rookie Football Development Program beginning on May 13.
Presumably, Franklin will not be able to participate in this weekend's rookie orientation camp either.
First round draft choice Datone Jones, who is also a product of UCLA, has reportedly already graduated and thus, isn't subject to the same restrictions.
Franklin could seemingly be expected to play a role in the Packers offense this season, but thanks to the presence of second round draft pick Eddie Lacy and holdover DuJuan Harris, the Packers don't necessarily need to rely on Franklin.
That could change if Lacy's injury history is problematic, but if everything goes according to plan, it won't be the worst thing in the world that Franklin misses part of the team's offseason program.
Franklin would be eligible to participate in training camp which starts in late July, and that's more important than OTAs.
UPDATE: The Green Bay Press-Gazette reports Franklin will take part in this weekend's rookie orientation camp. I understood the mandatory minicamp to be the one in early June.
