GLASGOW (AFP) - Scottish Cup holders Hearts crashed out of the competition after a last gasp Scott Wilson goal gave Dunfermline a 1-0 victory at East End Park.

With the game heading for a goalless draw and a replay, the Pars - who are rooted to the bottom of the Scottish Premier League - caused one of the shocks of the fourth round.

After knocking Rangers out in the previous round Dunfermline achieved yet another incredible result when centre-half Wilson rose to bullet home a header in the 90th minute.

And the defeat will further infuriate fans of the Tynecastle club, who have watched as some of their most influential players have been forced out by Lithuanian owner Vladimir Romanov.

With Steven Pressley and Paul Hartley already having been allowed to leave to sign for Celtic, the third player who had publicly criticised Romanov, goalkeeper Craig Gordon, was again left on the bench.

Steve Banks was between the sticks for the cup match and it now looks inevitable that Gordon will be allowed to leave the Edinburgh club in the summer.

In the other fourth round ties on Saturday First Division side St Johnstone achieved the result of the day with an emphatic 3-0 victory away to Premier League side Falkirk.

The Saints had been unfortunate to lose to Hibs in the semi-final of the League Cup after extra-time on Wednesday, but they made amends in style against their higher league opponents.

Peter MacDonald then caused further embarrassment for the Bairns by scoring a third in the second half.
