The men's 4x100m medley relay presentation has only just happened because one of the US swimmers struggled with exhaustion post race and needed medical treatment.

The young bloke is now well enough to stand for his gold medal and helping of Star Spangled Banner....

Michael Phelps had a tear in his eye. You do wonder is this really goodbye for him?

You are a long time retired and who wants to end on an odd number of gold medals! 23! Why not 24 or 25 or 26....hahaha.
