ParalympicsGB poster girl Ellie Simmonds will bid to be crowned Queen of the pool again today - but is still waiting to discover if she will face her main rival.
Simmonds, 17, became known as the darling of the pool at Beijing in 2008, when she won golds in the 100m and 400m freestyle at the tender age of just 13.
But she will wait to discover whether her world record-holding rival Victoria Arlen, also 17, is in today's S6 400m freestyle.
Earlier this week US swimmer Arlen was found to be non-eligible by the International Paralympic Committee (IPC) but she immediately appealed.
Arlen, who holds world records for S6 100metres and 400m freestyle, was reassessed and further information provided to the IPC about her disability.
It means Arlen will take part in the heats - but will be reassessed again following the race to see if she needs further re-classification, meaning she may not be allowed to race in the final.
