The Daily Telegraph's boxing correspondent Gareth A. Davies said Andrew Flintoff "looked like a complete, very raw novice, which is exactly what he is. A guy who's got a professional licence after only five months in the gym and no experience whatsoever of any boxing prior to that".
Freddie Flintoff has admitted his debut bout "wasn't one for the purists."
He said he was momentarily confused when, after being knocked to the floor, the referee asked him his name.
And after nearly five months of training, the former England cricket captain said he was looking forward to "such a good Christmas," but said he wouldn't make a decision on a future in boxing until 2013.
Bit sore today , the support from everyone out there made such a difference I can't thank you enough x
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
Andrew Flintoff has described his first boxing fight as an "out of body experience" after beginning his professional career with a win.
Sporting several bruises from his encounter with Richard Dawson, he told reporters:
I think I got the full experience. I got the canvas. I got a black eye. And I got the win. ... It was a bit wragged and arms going - I just wanted to leave it all in that ring.
