London Broncos will play their Super League match against Bradford Bulls at Adams Park and not at their own Twickenham Stoop.
The match will take place at the home of the London Wasps because of problems with the playing surface of the Broncos' venue due to recent adverse weather conditions.
The game was originally scheduled for Friday, April 5 but will now take place a day later at 3pm, as Harlequins will face Munster in the Heineken Cup quarter-finals at the same venue next Wednesday.
"Since the Hull FC game we have been working tirelessly to find alternative venues for the Catalan and Bradford games," Sky Sports News quotes chief executive Gus Mackay as saying.
"We have looked at all options including postponement and reversing the fixture, but this is the only option we have. We are grateful for Esher Rugby Club for hosting the Catalan game and the supporters that turned out at short notice for this match.
"However, this venue would not be suitable for the visit of Bradford Bulls due to its limited capacity. The pitch situation is something that is out of our control and we have been working with the RFL and Harlequins RU to source an alternative venue since last Monday. We have been reluctant to postpone these fixtures and cause a fixture backlog later in the season."
Broncos are currently 12th in the Super League table.
