WASHINGTON (AP) — President Barack Obama is bringing representatives of professional sports leagues, coaches, parents, youth athletes, researchers and others to the White House for a summit designed to help educate the public about youth sports concussions.

White House officials say the nation’s top sports fan is concerned that too little is known about the effects of head injuries in young athletes.

He’s also the father of two daughters who play sports.

At Thursday’s summit, Obama will announce pledges of money and other support from the NFL, the National Institutes of Health and others to begin doing the research, promoting safety and speeding development of materials designed to provide better protection.

Obama said last year that if he had a son he’d “have to think long and hard” about letting him play football.
