From the Laws
DENYING A GOAL OR AN OBVIOUS GOAL-SCORING OPPORTUNITY
Where a player denies the opposing team a goal or an obvious goal-scoring opportunity by a deliberate handball offence the player is sent off wherever the offence occurs.
Where a player commits an offence against an opponent within their own penalty area which denies an opponent an obvious goal-scoring opportunity and the referee awards a penalty kick, the offending player is cautioned if the offence was an attempt to play the ball; in all other circumstances (e.g. holding, pulling, pushing, no possibility to play the ball etc.) the offending player must be sent off
Should have been off but why expect
A. A referee to know the rules
B. NUFC to ever be given a penalty
C. Expect a decent referee to referee one of our games
