Burkina Faso's Jonathan Pitroipa (R) scored the lone goal that decided the match
Jonathan Pitroipa headed the winner in extra-time to send Burkina Faso through to Africa Cup of Nations semi-finals.
Togo's Floyd Ayite missed the only chance of the first half when the ball bobbled up off the woeful Nelspruit pitch and he scuffed his shot, reports the BBC.
After the break, Togo skipper Emmanuel Adebayor had a header cleared off the line by left-back Mady Panandetiguiri.
In a game of few chances, added time was needed and with 15 minutes left Pitroipa nodded in from a corner.
