Coleraine came within spot-kicks of extending their longest-ever run in Europe as 'Well keeper Trevor Carson kept out all three of their penalties - ironically, having been beaten twice from the spot in normal time as the hosts recovered from a 2-0 deficit to draw 2-2 after full-time and extra-time.
The Bannsiders were two goals behind at the break, with visiting strike partnership Callum Lang and Tony Watt both on target, but a much-improved second half saw them pull level through a pair of Ben Doherty penalties, with Bevis Mugabi sent off for conceding the second on Eoin Bradley.
The substitute would then strike the crossbar in added time as Coleraine pushed for another famous victory, but having held their Scottish Premiership hosts over 120 minutes, saw all three kept out by Carson as Stephen Robinson's side squeezed through.
