Luke Moore's second goal of the season has given AFC Wimbledon a 1-0 half-time lead over Wycombe Wanderers at Kingsmeadow.
Wycombe are down to 10 men after having Stuart Lewis sent off for serious foul play.
Lewis was given his marching orders by referee Gavin Ward on 34 minutes following a nasty tackle on George Porter.
Wimbledon broke the deadlock three minutes later when Callum Kennedy's cross was headed into the corner of the net by the in-form Moore.
