Inverness CT 1 Celtic 0
Inverness Caledonian Thistle upset Celtic 1-0 in the Scottish Cup quarter-finals today in a repeat of the first division club's greatest ever win.
A first-half strike from Dennis Wyness handed Caley - who won 3-1 at Celtic Park in the Scottish Cup three years ago - a semi-final place with their victory over the Scottish champions.
The home side had to withstand some torrid pressure from UEFA Cup semi-finalists Celtic in the second half but hung on grimly to cause the tournament's biggest upset.
Caley are joined in the last four by Motherwell after they beat Stranraer 4-0 on Saturday.
Rangers and Dunfermline Athletic have to replay their match tie a 1-1 draw at East End Park earlier on Sunday, while Dundee and Falkirk shared the same scoreline and will also replay.
