Horndean lost 1-0 to GE Hamble in the Wessex League premier division and had striker Billy Huntley sent off at Five Heads Park.
Huntley received a straight red card for pushing an opponent in the face after just six minutes, leaving the home side with a mountain to climb.
Dave Carter’s side held out until the 76th minute, when Lewis Fennemore cracked home a superb volley from a half-cleared corner.
‘We did well and more than matched the team third in the league with only 10 men,’ said Carter.
‘By the letter of the law our player had to be sent off but it was a nothing incident really.
‘We also feel we had a blatant penalty turned down late on.
‘Defensively we remain very solid and have only conceded 10 goals in 11 games.
‘The ball just won’t go into the net for us but I am sure that will change soon.’
Dan Martin had an excellent debut on the left flank after joining from Hayling United in midweek.
His old club battled back from their midweek traumas to earn a 1-1 draw at Totton & Eling.
Hayling needed to restore some pride following their 9-0 mauling by Winchester City and did so with a dogged performance.
Josh Case converted a penalty, awarded for handball 15 minutes from time, to seal the draw.
Youngsters George Vince and Aaron Kinchin were outstanding and the return of Jack Salter-Vaile made a big difference.
Moneyfields went down 2-1 against a lively Bemerton Heath Harlequins.
The Copnor club are without a win since September 10.
Manager Miles Rutherford said: ‘We looked lethargic and half-paced. It’s just not acceptable.
‘We lacked concentration and in the end we got punished.
‘There were no excuses – Bemerton were the better team.’
Moneys took the lead when Rob Evans netted in the 11th minute.
Harlequins equalised just before the break as Graham Mankin struck.
The decisive moment came after 75 minutes.
Graeme Gee failed to clear and Joe Sanger did just enough to nudge the ball home.
