The Briton looked to have no hope of getting to his feet but unbelievably rose off the canvas, to the astonishment of Wilder and the Staples Center crowd, to survive the count and hang on until the end.
"I was evaluating these guys throughout the whole fight (and) in the 12th round, they'd boxed their hearts out, threw a lot of punches but there wasn't a lot of heavy damage taken by either guy", Reiss said in an interview with SiriusXM Boxing. "Jack I'm OK" or whatever".
Responding to accusations he gave Fury a longer count than usual, Reiss said: "The 10 count doesn't mean 10 seconds".
"I said, "Do you want to continue?', he said 'Yes" and put his arms on my shoulders".
Pregnant Meghan Markle makes surprise solo appearance
Details of the outfit worn by the Duchess of Sussex yesterday have emerged - some 24 hours after the surprise solo engagement. Meghan adds: "Togetherness at its finest", while the crowd chuckle through the awkward conversation.
Reiss has been criticised for allowing Fury too much time to recover.
It looks like we're going to have to wait a while longer to see an undisputed heavyweight champion.. As The Ring's report explains, that figure doesn't include pay-per-view buys in the United Kingdom - of which there were certainly many - or digital purchases made on platforms such as Playstation 4.
If the sales go through 300,000 Wilder and Fury are set to earn more than US$7m ($4m for Wilder, $3m for Fury) as their purse guarantees.
The break-even point for this pay-per-view was reportedly 250,000 buys, meaning anything north of that mark is a win, particularly for Tyson Fury and Deontay Wilder, who will pocket a portion of the pay-per-view sales in addition to their guaranteed purses. He is in camp now in America, and he would love to fight Fury, he would.
