David Haye valiantly soldiered into the 11th round despite badly injuring his Achilles in the sixth round, and the extent of the injury has emerged online.
Tony Bellew ultimately inflicted Haye with his third professional defeat after trainer Shane McGuigan threw in the towel in the penultimate round.

Bellew produced a huge upset by beating Haye in their grudge match over the weekend, and the grueling fight has seen both men pocket cool seven-figure cheques.
Months of barbing finally culminated last Saturday night as they waged war at the iconic O2 Arena. A tentative start was subsequently followed by an explosive 6th round.
As a result of the injury, Haye's movement was severely hampered for the rest of the fight. And Bellew took full advantage by delivering an onslaught before McGuigan pulled his fighter from the bout.
Following the fight, Haye underwent surgery releasing this message;
"David underwent surgery to his right Achilles this afternoon, after completely rupturing the tendon during Saturday night's fight with Tony Bellew. David would like to thank everyone for their many messages of support, as well as the staff at the hospital."
And this was the mess his Achilles was in. This is gruesome:
The 36-year-old experienced his first stoppage defeat since 2004, but according to Carl Froch, Haye is hellbent on avenging his 11th round loss.
"I don't think it's the end of him. I spoke to David Haye earlier and he's out of the operation, he's out of theatre." Froch told Sky Sports News via The Mirror.
Haye, who held the WBA heavyweight world title from 2009-2011, is eager to re-claim the heavyweight title but not before he gets in the ring with Bellew again.
"He's told me he wants to come again - 100 per cent. He said to me, and I quote, 'I will win a heavyweight world title, but I want the rematch with Bellew first'."
Get well soon, David.
