Tigers are urging supporters to join the campaign and safeguard children's heart services at Glenfield Hospital, which is currently under threat as part of a national review.
Under the four options being put to the public, some of the existing centres will no longer carry out operations.
The East Midlands Congenital Heart Centre (EMCHC), at Glenfield Hospital in Leicester, is included in just one of the four options. The centre, which already serves a population of nearly five million, is in ‘option A’ which was rated the highest scoring option by the expert review team.
Tigers player Geoff Parling said: "We have always supported Leicester's Hospitals and last year we went to the children’s wards at Glenfield Hospital where we saw first hand what a great job they are doing.
"It's important that local services are safeguarded for young patients who have undergone care there as well as for future children who might need the lifesaving service.”
A public consultation is now underway which includes a consultation event on Thursday, June 16 at the Walkers Stadium.
Giles Peek, head of the centre at Glenfield Hospital, said: "We are delighted to be supported by Leicester Tigers and urge all their fans to join them by registering their support online."
