FA Women's Cup fourth round
Reading 2-2 Charlton Athletic (aet), Charlton won 5-4 on penalties
Charlton belied their shot-shy reputation by taking a two-goal lead, Jenny Newman hitting the first after only seven minutes before then setting up the second for Francesca Ali seven minutes before the interval.
But the game turned when Roberts was sent off for handling the ball on her own goal-line.
Mikaela Howell slid home the resulting penalty and then Stacey Wiggins headed a 62nd-minute equaliser.
Despite the Premier League's second-placed side pressing for a winner, the Addicks held firm and then kept their nerve to win the shoot-out.

Emma Beckett wrapped up victory with the final goal 13 minutes from time.
