Wigan Warriors' "home" Super League fixture against Widnes has been switched to the Vikings' Select Security Stadium - 17 hours after Wigan postponed the game.
Widnes, who were not consulted about Wigan's initial cancellation, will now visit the Warriors on Sunday, 2 July.
Friday's game will begin at the original start time of 20:00 GMT.
The Rugby Football League will investigate Wigan for a potential breach of operational rules.
Unlike Wigan, Widnes have an artificial surface at their ground which is unaffected by the Storm Doris weather.
Turn of events
Following the deterioration of the surface at the DW Stadium on Thursday because of Storm Doris, the Warriors and fellow tenants Championship football side Wigan Athletic concluded that of the back-to-back home fixtures on Friday and Saturday, the Latics' match against Nottingham Forest would be more difficult to rearrange than the Widnes fixture.
However, the decision to publicise the postponement was done without consultation with Widnes or the RFL.
The RFL spoke with the clubs late on Thursday, stating the rescheduling of the match was down to them, and the decision was publicised on Friday that the game would go ahead, with a reversal of the schedule and reduced prices for fans.
"Having requested and received compensation from Wigan Warriors to help mitigate the commercial loss, the club felt that it should make a gesture to both sets of supporters," Widnes chief executive James Rule said.
What are the operational rules relating to a postponement?
Under the RFL tier 1-4 rules, which include Super League, it states: "Matches shall only be postponed in accordance with the Operational Rules and the Match Day Operations Manual."
Any postponement requires a pitch inspection by RFL personnel, usually the appointed Match Commissioner.
