(BBC) - What would you do if you saw a player lying on the pitch, blood all over their face and not moving?

Chelsea's John Terry was lucky to recover so quickly from unconsciousness in the Carling Cup final after an accidental kick in the head.

But most football teams don't have the benefit of professional medical teams so what would you do if it happened in a game you were playing in?

Reading's physio Jon Fearn reveals what the basic response should be.

When a player goes down with a head injury the first priority is not to move them. Neck and spinal injuries are easily made worse by this so leave them where they are.

However, if they are unconscious their life is at risk so some movement may be deemed necessary. This should be left to trained personnel only.

Call an ambulance immediately if at any stage you feel a major trauma is involved or are unsure what to do. Grab a member of public to do this if you have to.

There is likely to be someone with first aid qualifications at the game to administer basic attention but it is always better to be safe than sorry.

Top paramedics and medical staff are always available for action at professional games, so that is why it is crucial for any amateur team to have someone trained in basic first aid.

Open eyes does not necessarily mean the player is conscious. The best way to check for this is their responses.

Speak to them, say their name, or just tap them on their shoulder. Look for a reaction.

If they fail to respond then call an ambulance.

However, there are still a few things you can do to help before professional medical help arrives. Remember the ABC guide.

A clear airway, breathing and circulation are all vital for anyone to be alive and each needs to be considered in turn when dealing with the injured player.

A clear airway is required for oxygen to reach the lungs.

A big danger is for the player's tongue to relax and fall back into the mouth. If this happens, the best thing to do is the chin lift.
