Odd/usual injuries during basketball games

[Bad Zebra]

Not really odd, but kinda scary. Girls middle school three years ago. Two players dive for loose ball and bonk heads. Both get up. One seems a little more dazed than the other and comes out of the game, rubbing her head and giggling from embarassment. Five minutes later, she collapses on the sideline. Game stopped. Ambulance called. EMT's arrive and immobilize her head/neck as a precaution because it is a head injury and she is AIRLIFTED out of the parking lot by a medical chopper to the closest hospital with level 1 trauma unit. Game continued after a half hour delay.
