The referee will be Martin Atkinson (West Yorkshire)
His last Villa game saw us play Spurs at home, when he dismissed Defoe for a deliberate elbow. In total, Atkinson has shown 8 red cards in 27 games, 'bettered' only by Phil Dowd and Anthony Taylor, who have shown 9 and 10 reds respectively in 26 matches.
The last time Blackburn had the pleasure of Mr Atkinson was back in January, as they lost at Stamford Bridge.
He will be assisted by Glenn Turner (yellow flag) and Gary Beswick (chequered flag). The 4th official is Lee Probert.
