Ref Illerton booked captain Cliff Byrne for a tenth minute foul clearly committed by defensive partner Butler, and faced a two-match ban as it would have been his tenth yellow card of the season.
The Butler did it
But the referee agreed to review the incident on video and has agreed that he got the wrong player, transfering the card to Butler.
Although Byrne escapes a two-match suspension, it does leave Laws looking to fill a gap left by Butler as he misses one game.
Midfielder Matthew Sparrow will also start a two match ban next week, while Terry Barwick must sit out this weekend's visit of Northampton through suspension.
