Cardiff City have called on the Football Association to investigate the incident which saw Roger Johnson caught in the throat by Crystal Palace defender Claude Davis.
Johnson was taken to hospital and kept in overnight following a challenge by Palace's on-loan stopper Davis during Cardiff's 2-0 win at Selhurst Park on Saturday.
Bluebirds boss Dave Jones was sent to the stands at half-time after admitting he tried to speak to Davis about the incident.
Jones was unhappy with the challenge and now Cardiff chairman Peter Ridsdale has asked the FA to look into the matter.
"We have now had the time to review the video footage of the incident where Roger Johnson was 'elbowed' in the throat by Claude Davis in our match at Crystal Palace on Saturday 11th April 2009," said Ridsdale in a statement on the club's official website.
"In our opinion, the challenge looks deliberate and malicious and could have more seriously endangered Roger Johnson's wellbeing than hopefully is the case. We are now asking the Football Association to investigate as a matter of urgency.
"If that incident had happened off the field of play, the police would have been asked to view the video with a view to considering assault charges. Any further comment will only be made once we have had a response from the FA."
Speaking after the game, Palace boss Neil Warnock cleared Davis of any malicious intent and believes the player will escape punishment.
Warnock said: "Claude didn't elbow him. If anything, he ran into his arm.
"I don't think Claude will get done for that. There was no arm movement at all."
