Oxford United boss David Kemp has leapt to the defence of Chris Hackett after the 17-year-old was sent off after just 20 minutes of Saturday's match at Bury, writes Mark Edwards.

Hackett was shown the red card by referee Mark Clattenburg for alleged use of his elbow on Bury's Chris Armstrong as the players challenged for a high ball.

Armstrong fell to the ground as if he had been shot, and a 21-man melee ensued.
