Tommy Armstrong entered mini-camp as a running back, but he'll be sticking around at another position.

The former Nebraska quarterback was offered a tryout with the Minnesota Vikings during the three-day camp, and according Armstrong while speaking with the Pioneer Press, he'll be sticking around as a safety during spring workouts and OTAs.

“I’m invited back to OTAs (organized team activities) with the team,’’ Armstrong said via Chris Tomasson of the Pioneer Press. “I’m excited about it.

According to Tomasson, Armstrong has yet to be offered a contract, but that could change should he continue to impress during OTAs. The former signal caller is back in Lincoln, however he's already looking forward to his return to the Twin Cities.

“I met with (defensive backs coach Jerry) Gray after practice Sunday, and he said, ‘We’re going to fly you back up here (next) Sunday and we’ll give you a playbook,’’’ Armstrong later added. “He said he’d call me in a few days. They also like the way I’ve been playing special teams.’’

Despite having not played the position since his high school days in Texas, the former quarterback is excited about making the transition to the other side of the ball. The Nebraska product is determined to make his way in the NFL by any means necessary, whether that's on defense or on special teams.

“I was kind of rusty at first,’’ Armstrong said after his day at safety. “But I think that I can bring something to the team on the defensive side of the ball and to special teams. I’m looking forward to next week. I’ll do whatever it takes to play in the NFL.’’
