The Vikings, back to work at Winter Park after Memorial Day weekend, continued to get their 2017 draft class under contract Tuesday.

Throughout the day, they announced the following players had signed rookie contracts: third-round center Pat Elflein, sixth-round tight end Bucky Hodges, seventh-round linebacker Elijah Lee, seventh-round wide receiver Stacy Coley and seventh-round safety Jack Tocho.

That's now 10 of their 11 draft picks under contract.

The only Vikings draft pick yet to put pen to paper is running back Dalvin Cook, a second-round selection who was the team's top pick a month ago, but Cook is also expected to sign soon.

In other news, the Vikings have signed former Nebraska quarterback Tommy Armstrong, who will play safety for the Vikings. Amstrong, who threw for 2,180 yards and rushed for 512 for the Huskers in 2016, participated on a tryout basis in rookie minicamp a few weeks ago.

To make room for Armstrong, the Vikings waived wide receiver Mitch Mathews. Mathews signed with the Vikings only a couple of months ago.
