The Vikings officially signed 15 undrafted free agents following the weekend's NFL Draft.
The list is similar to the one released on Saturday night after the draft, with some slight differences.
The most well-known of those undrafted free agents is former Northwestern quarterback Kain Colter, who the Vikings signed as a wide receiver.
In college, Colter was known for his versatility. He ran for 2,180 yards and passed for 2,166. He also caught 63 passes for 683 yards and four touchdowns.
He worked out as a receiver at both the NFL Combine and the Senior Bowl, according to Pro Football Talk.
But it was off the field where Colter really made a name for himself recently. He led an effort of Northwestern players to form a union and argue for basic employee rights.
Those efforts paid off, in March, when the National Labor Relations Board ruled the players had the right to organize.
The rest of the list includes: G Conor Bofelli, T Pierce Burton, DE Rakim Cox, DT Isame Faciane, WR Donte Foster, T Matt Hall, C Zac Kerin, TE AC Leonard, WR Erik Lora, QB Travis Partridge, T Antonio Richardson, DE Tyler Scott, DE Jake Snyder and RB Dominique Williams.
To make room for those undrafted free agents the Vikings released four players.
According to the Star Tribune, the Vikings waived running back Bradley Randle, guard Josh Samuda and linebackers Terrell Manning and Simoni Lawrence.
None of the four played a single snap for the Vikings last season.
