CLEVELAND — LeBron James called it a “slight” headache, though nothing involving the game’s best player is ever minor.
So when James got a cut on his head after falling into a TV camera in Game 4 of the N.B.A. Finals, it led to questions about how the N.B.A. treats head injuries and whether someone taking pictures should be close enough to cause one.
The league tried to deal with both issues long before Thursday night.
Baseline photography positions were already reduced last summer, and a concussion protocol was previously put in place. But according to the league’s policy, a cut on the head alone is not a trigger for it.
