The Vikings have now signed five defenders from the now-defunct Alliance of American Football league that played its last game on March 31.
Safety Jordan Martin and linebacker Greer Martini are the latest to sign entry-level contracts with the cap-strapped Vikings. Minnesota has now filled 67 of 90 spots on the offseason roster with eight picks in the upcoming NFL Draft.
Martin, 24, had four pass deflections and one interception in eight games for the San Diego Fleet. He went undrafted last year after starting games as a cornerback for Toledo and safety as a graduate transfer to Syracuse. Martin is the fifth safety on the roster with Harrison Smith, Anthony Harris, Jayron Kearse and Derron Smith.
Martini, 23, spent last preseason with the Packers as an undrafted free agent out of Notre Dame. He most recently played for the Salt Lake Stallions, making him a former teammate of defensive end Karter Schult, who signed with the Vikings on Tuesday.
