Tua Tagovailoa practiced Wednesday for the first time since suffering a concussion in Week 2, and the Dolphins are aiming for him to start Sunday against Arizona.

This time of year, during football season, concussion prevention is a big topic. You may have also noticed the NFL taking an extra step to keep players safe. Some players have opted to wear the “guardian cap.”

SWEENY, Texas – Football is king in Texas, and as high school teams gear up for another season, so does the debate about preventing concussions. Last season, the Sweeny High School football team began using different helmets during practice. The helmets are made by a company called Guardian Cap. The maker of Guardian Cap said his company's tests prove the product does reduce the impacts of hits to the head. However, based on the statement from the committee on standards for athletic equipment, Sweeny High School's athletic director said the team will not use them this season.
