TALLAHASSEE, Fla. (AP) - The Florida House has unanimously passed a bill requiring coaches and others to pull student athletes from play or practice after a head injury.
    
The bill (HB 291) was approved 116-0 on Thursday. It also prevents any student athlete from returning to competition after a head injury until given the all-clear from a physician. The measure ensures that parents or guardians sign an "informed consent" form about the dangers of concussions before a student can join a team.
    
The issue of student athlete concussions - essentially when the brain bruises from knocking against the inside of the skull - has risen in importance in recent years.
    
Multiple concussions over time can cause irreversible brain damage. Victims suffer problems in thinking and in controlling emotions, among other problems.
