NHK has learned that police have received a complaint about a serious foul committed during an American football match between 2 Japanese university teams.
During the May 6th game in Tokyo, a Nihon University defender tackled a Kwansei Gakuin University quarterback from behind after the player had thrown a pass. The quarterback suffered injuries that will take 3 weeks to heal.
Investigative sources say the injured player reported the incident to the police.
On Saturday, the head coach of the Nihon University team, Masato Uchida, apologized and said he intends to resign.
But Uchida did not comment on an allegation that he instructed the defender to commit the foul. He said he will respond to that question in writing.
The father of the injured Kwansei Gakuin quarterback says he is not satisfied with Uchida's response because he didn't explain why the defender carried out the dangerous tackle.
Tokyo police are expected to launch an investigation of the case.
