Gov Jerry Brown on Monday signed into law AB 2127, which bans football teams at middle and high schools from holding full-contact practices(对抗性训练) that exceed 90 minutes a day. The new law limits the number of full-contact practices during the season to two per week and prohibits contact practices during the off-season. 

The new rule, which takes effect Jan. 1, 2015, is designed to help reduce concussions(脑震荡) and other serious brain injuries.

Assemblyman Ken Cooley, who sponsored the bill, said, “AB 2127 will reassure(使……放心) parents that their kids can learn football safely through three hours of full-contact practice … to make the most of conditioning and skill development while reducing concussion risk to the least.” He added that 19 other states already ban full-contact practices in the off-season.

Nearly 4 million high school students nationwide suffer head injuries every year, according to the US Centers for Disease Control and Prevention. The law will come up following a new rule, going into effect this fall, which restricts California high school coaches from holding practices for more than 18 hours a week.

Some high school coaches say the new law and rule will interfere(妨碍) with their ability to field a quality team that is properly prepared to avoid injury.

Javier Cid, coach of the football team at Los Angeles Roosevelt High, said they need to hold full-contact practices. “We do need to figure out who can play. That’s a very important part of our summer practice. That’s how we determine who our starters(上场人员) will be,” Cid said.

Sen Joel Anderson voted against the new rules, saying the legislature should not be telling local officials how much time should be devoted to full-contact practices. “I expect high school coaches to use common sense,” Anderson said. “I expect them to be professional. I expect them to look at and understand their athletes and I expect them to protect their athletes to the best of their ability.”
