Former Nebraska quarterback Tommy Armstrong won’t be signing with the Vikings.

Armstrong tried out for the Vikings at a rookie minicamp last week as a running back and a safety. He said last Sunday that defensive backs coach Jerry Gray told him he would be brought back for organized team activities as a safety, but he tweeted Thursday night that it won’t happen.

“Unfortunately I got the call that they couldn’t make a second cut for me!!!” Armstrong tweeted. “Just want to say thank you to the @Vikings for the chance!!”

Armstrong then sent a text message to the Pioneer Press that read, “Things just didn’t work out. Couldn’t make a cut for me.”

The Vikings have not signed any players who tried out. On Wednesday, they waived tackle Nick Fett, who had signed last week as an undrafted free agent, but it was to clear a roster spot to sign free-agent wide receiver Michael Floyd.

After starring at quarterback for the Cornhuskers, Armstrong has known he must change positions to make the NFL.

“I’ll do whatever it takes to play in the NFL,” Armstrong said last Sunday.
