The signing has been expected for the past two days. Vasher was recently cut by the Chicago Bears and is expected to provide depth in San Diego's secondary. The team also signed free agent Donald Strickland since Antonio Cromartie was traded to the Jets earlier this month. Vasher and Strickland are expected to backup starters Quentin Jammer and Antoine Cason, who is poised to replace Cromartie.
Vasher, 28, had early success in his career, but has been injured in recent seasons. He played for San Diego defensive coordinator Ron Rivera and secondary coach Steve Wilks in Chicago.
“In Nathan Vasher, we’re adding a proven NFL player with experience in the league,” San Diego general manager A.J. Smith said in a release sent out by the team.
