Charlton and Plymouth could be on course to meet in a play-off for a place in the Sky Bet League One play-offs if they can’t be split after Saturday evening’s final round of matches.
The EFL are set to announce plans for the potential fixture and title sponsor Sky Bet have priced it up as a 500/1 chance.
Plymouth are currently three points behind sixth-placed Charlton but would finish level on points, goal difference, goals scored and goals conceded if they win 2-0 and the Addicks lose 0-4, or both results are decided by the same equivalent margins.
With Lee Bowyer's Charlton travelling to relegation-threatened Rochdale and the Pilgrims visiting Gillingham, who have little to play for, the EFL are planning for the prospect of a decider at a neutral venue before the play-offs begin on May 10.
Sky Bet offer 500/1 for the play-off for a play-off to happen.
While the match occurring seems unlikely, Plymouth are already defying odds of 5,000/1 from November, when they were in the relegation-zone, to be in contention for promotion.
Shrewsbury would await the winner of the unprecedented fixture after missing out on automatic promotion and surely hold an additional benefit of their opponents facing three games in six days.
Plymouth manager Derek Adams is fully aware of the prospect of the fixture and is not dismissing the prospect.
He told the Plymouth Herald: "That's the most unlikely option. We know what the score has to be for us, and we know what has to be at Rochdale for that to happen, but it's not far flung as people would think."
