Stockport County have threatened to take legal action against Colchester United defender Paul Reid.
Hatters boss Jim Gannon has said he will report Reid to the police after a challenge which saw Matt McNeil carried off with concussion on Saturday.
Gannon told BBC Radio Manchester: "We are collecting all the evidence and presenting it to the police.
"It's up to them to take criminal proceedings against the player in question," he added.
McNeil was taken to hospital but has since been discharged.
Speaking about the incident, in which Reid was booked, Colchester boss Paul Lambert told BBC Essex: "The two of them have challenged for the ball and the lad's got there before him.
I think we're the cleanest team in the league with the least amount of fouls but probably receive the most amount of fouls against us

"Reid has come over and headed the back of his head but hopefully the lad is okay."
Meanwhile, Gannon has praised his players for sticking to skilful principles despite some opponents' physical approach.
He said: "The players kept coming back and played with skill and invention.
"We play the game in the right manner. We hope the game punishes those that don't play in the right manner.
"Looking at the match stats overall - not just the stats in terms of the possession we had and the corners and shots on target - they show that we're a clean team that don't give away fouls.
"I think we're the cleanest team in the league with the least amount of fouls but probably receive the most amount of fouls against us."
