HELENA, Mont. -

School coaches could be facing more stringent rules when dealing with student athletes who suffer a concussion.
    
The Montana Senate on Friday endorsed a plan that aims to better protect high school athletes from the dangers of concussions. It has been adopted in 43 other states.
    
Senate Bill 112 requires more training to identify concussions. It also requires schools to pull a player out of a game if the player exhibits symptoms of a concussion.
    
Supporters say it is a needed remedy for a problem that long went misunderstood and ignored.
    
But opponents say the bill creates rules difficult for small schools to implement. They point to a requirement that athletes are cleared by a health-care provider before being allowed to return to the field.
