The Saints made a pair of roster moves by waiving defensive end Mitchell Loewen and officially signing tight end Garrett Griffin.

Loewen, who was seen wearing a walking boot at recent organized team activities, was waived with a non-football injury designation.

Griffin, a tight end out of Air Force, caught 41 passes for 678 yards over three collegiate seasons. He also has the ability to serve as a long snapper.

The Saints intention to sign Griffin has been known for several weeks.

Griffin has a commitment to the Air Force and is waiting to find out if he will be ruled a reserve, which would allow him to play for the Saints. A source indicated that this is the likely outcome.

However, he could also be called back, which would put his football career on hold.

United States Secretary of the Navy Ray Mabus announced last month that former Navy quarterback Keenan Reynolds will be allowed to play after the Baltimore Ravens used a sixth-round pick on him, and Mabus also cleared Navy graduate Joe Cardona to return to the New England Patriots.
