Andrew Flintoff's former England captain Michael Vaughan - who is trying his own hand at a different physical test on the Strictly dance floor - has led Twitter praise of his old teammate.
Night all...what a day!!! Samba,double dip spray tan and @flintoff11 wins a boxing match....
Former England batsman Adam Hollioake, who entered the worlds of professional boxing and mixed martial arts after his cricket career ended, singled out Flintoff's strength in fighting back to claim victory.
Congrats to my man @flintoff11 to win is a gr8 effort but to get off the canvas to win shows your character
While celebrity Flintoff fans also weighed in with their own compliments:
One of the gutsiest things I've ever watched. Take a bow, Andrew Flintoff! @flintoff11
