Falkirk knocked holders Celtic out of the CIS Insurance Cup after a penalty shoot-out miss from Evander Sno. But Falkirk replied within a minute, Anthony Stokes firing home after Alan Gow's effort was deflected. Both sides scored four penalties and missed two before Jack Ross made no mistake to put pressure on Sno, who shot wide of the post.
Falkirk came close to breaking the deadlock when Gow rounded goalkeeper Artur Boruc, but Gary Caldwell cleared the forward's effort off the goal-line. And Gow's drive was parried by Boruc to O'Donnell, who sent his diving header wide of the post. A Stokes drive struck the post, bounced off Boruc's back and O'Donnell was ruled offside after slotting home the rebound.
Zurawski put Celtic ahead from six yards eight minutes into extra time, but the in-form Stokes replied almost instantly. A Vennegoor of Hesselink header struck the Falkirk post, while a Stokes drive forced a fine save from Boruc as both sides pushed for a winner. Boruc produced a fine save in the dying seconds following a Stokes header, but the match went to penalties.
Both sides had scored three apiece before efforts from Stokes, Caldwell, Gow and Kenny Miller were saved. Vitor Lima, Zurawski and Jack Ross made no mistake before Sno's miss sent Falkirk into the semi-finals.
