Swansea City players have been forced to undergo emergency inoculations following an outbreak of measles in the area.
MMR jabs were administered to the squad after it had been revealed that over 1,000 residents in South-West Wales had been diagnosed with the illness.
"Given that the club is in the outbreak zone, we had a thorough check of which players had not received their second jabs," Wales Online quotes a Swansea spokesman as saying.
"We're not in a position to say who or how many received the inoculation, but I can confirm that all players and officials in the club are now up to date. Similar measures have been rolled out to youth players and letters have also been sent out to parents reminding them of the situation."
The Swans are due to take on Manchester City this Saturday.
