In a story headlined “Is my kid too young for contact sports?” that appeared Tuesday on Page B1, The Associated Press reported that new guidance from an expert panel’s consensus statement on concussions shows there is not enough solid evidence to answer some of parents’ most burning questions about contact sports, including what age is safest to start playing them. The story should have included that several of the authors of the guidance reported receiving grants, gifts, consulting work or personal fees from amateur and professional sports leagues and associations.

In addition, their work was paid for by US Lacrosse, USA Football, USA Rugby and the American College of Sports Medicine. The funders had no role in how the study was done.
