Tyson Fury's world heavyweight title fight against Wladimir Klitschko on Saturday is set to go ahead after a row over the thickness of the canvas.
Fury, who will face the WBA, IBF and WBO champion at about 22:00 GMT, had complained the canvas was "too soft".
The underlay in the ring in Dusseldorf, Germany, has been torn up and the canvas re-laid which could result in a fight on the undercard being lost.
Fury's agent Asif Vali tweeted: "It's on after two hours, it's fight time."
Singer Rod Stewart, who is set to perform in the build up to the fight, was also inconvenienced after his soundcheck was delayed because of the last-minute canvas alterations.
Vali said British challenger Fury had complained to both the British Boxing Board of Control and the commissioner of the fight about there being too much foam under the canvas.
Fury, 27, and his camp believed it to be five inches thick, which Vali said was a health and safety issue.
Fury the new world champion ...for a long time !
