Colin Byrd, 17, of Kansas City, is charged with misdemeanor assault.
According to the Platte County prosecutor's office, Byrd ripped off another player's helmet and hit him in the head with it. The alleged assault happened during a game between Byrd's Platte County R-III team and Winnetonka in mid-October.
"Football players consent to physical contact and the possibility of injury every time they walk onto the field. And even conduct that draws a penalty is almost never criminal. In this case, however, we allege what happened that night was not football," said Platte County Prosecuting Attorney Eric Zahnd said.
Byrd was ejected from the game after a flag was thrown.
The other player, according to the prosecutor's office, suffered a significant injury, which led to a concussion. The individual is still under a doctor's care and has not returned to school.
Boyd faces a maximum of one year in jail if convicted.
