UND's linemen looked a bit different when they walked onto Memorial Stadium's turf for practice Sunday morning.
Their green Fighting Hawks helmets were hidden behind a white, padded covering.
UND debuted the helmet coverings, which are designed to help prevent concussions and reduce impact to the head, during the third practice of fall camp. The Fighting Hawks didn't wear them Friday or Saturday, because the team was practicing without pads on those days.
On Sunday, UND wore shoulder pads for the first time this fall.
"Talked to a few people using them around the country and visited with those guys at the national convention last year," Schweigert said. "We're just trying to keep our guys safe, so we can be safe, practice, so we aren't missing practice due to (concussions). We want to try to do the right thing to keep our guys safe."
UND's offensive and defensive linemen wore the helmets. So did linebacker Jaxson Turner.
Schweigert said the plan is to use the helmet coverings often in practice.
"Whenever there's going to be a heavy contact practice, (we'll wear them)," Schweigert said. "When we were helmets only, we just didn't feel like we'd have that contact."
That changed Sunday.
"With the shoulder pads on, it's going to be a more physical practice," Schweigert said. "When you do some inside drills, more run game, those types of things, it's more physical."
