Sky has apologised to customers after its coverage of David Haye's fight with Wladimir Klitschko was hit by technical problems.
The broadcaster said it had an "issue" with new telephone and online bookings for last night's world heavyweight unification bout due to "unprecedented demand".
The glitch meant many sport fans were unable to order the £14.95 pay-per-view fight.
During the contest, which saw British fighter Haye lose in Hamburg on points, Sky's Twitter feed urged those experiencing problems to "please find your nearest pub".
A statement posted on Sky's website following the match said: "We are sorry to have disappointed any viewers who were unable to order Haye vs Klitschko.
"Sky had an issue during the evening with new telephone and online bookings for the fight.
"We had encouraged early booking over three weeks leading up to the fight, through a range of media including on-air promos and press advertising.
"However, we experienced unprecedented demand on the night and whilst early telephone and online purchases worked there were issues with late bookings through these routes on Saturday."
Sky said free replays of the fight will now be available to all customers at 9am, 1pm and 7pm today.
