MANKATO -- Linebacker Ben Leber has yet to sign as a free agent but that could happen soon.

According to ESPN's John Clayton, the Seattle Seahawks are one of four teams vying for Leber's services. It's not clear at this point if the Vikings are in that mix. The 32-year-old Leber, who signed with Minnesota as a free agent in 2006 after four years in San Diego, has been the Vikings starting weak-side linebacker.

Erin Henderson will get the first shot at that role in training camp.
