England swaggered into Murrayfield emboldened by a run of 24 wins from 25 Tests but were caught cold by Scotland's intensity and ambition with World Cup-winning captain Martin Johnson blaming complacency.
New footage has emerged of Owen Farrell pushing past Scotland players before a melee erupted at Murrayfield. England scrum-half Danny Care admitted afterwards that the spark between Farrell and Wilson had "fired up the boys even more", although head coach Eddie Jones said he was unaware of the incident.
Television footage appears to show a clash between England centre Owen Farrell and Scotland No. 8 Ryan Wilson that ended when they were pulled apart by teammates.
Jones, a star in the making, kicked forward and gathered to ground in the 15th minute for Scotland's first home try against the English since 2004.
His long pass from just outside the 22 released Jones who sprinted clear before being tackled by wing Jonny May.
Winger Sean Maitland crossed for the other try - from a move started by Jones' 60 metre break down the right.
Laidlaw missed the tricky conversion but Scotland led 15-6.
The UK's Sky Sports report that the RFU will back Farrell against any potential claims that he instigated the melee which occurred before Scotland's first victory over their oldest foe since 2006. "If there was (an incident), we shouldn't let that detract from a great Scotland victory", Jones said after the game.
Replacements: 16 Jamie George, 17 Joe Marler, 18 Harry Williams, 19 George Kruis, 20 Sam Underhill, 21 Richard Wigglesworth, 22 Ben Te'o, 23 Jack Nowell.
