Leicester's captain was probably influenced (and still outraged) by the referee's earlier inexplicable sending-off of Beckford (53rd minute) - a decision later overturned by the FA. Three men sent off in all - very poor officiating. Can't really tell from this angle whether Sparrow deserved to be sent off, but it was so late in the game (85th minute) that it had little effect on the outcome. Beckford's dismissal, however, arguably cost Leicester 3 points, given his superb recent form.
Pathetic Leicester captain shouting and screaming like a toddler to get Sparrow sent off. 50/50 ball, both slid in, one player gets a red card, what a joke.
