Soccer-Aberdeen knock holders Celtic out of Scottish Cup

Feb 8 (Reuters) - Celtic, unbeaten in 24 matches at the top of the Scottish Premier League, were knocked out of the Scottish Cup with a 2-1 home defeat by Aberdeen in a fifth round tie on Saturday. Aberdeen came from behind to upset the holders who went ahead after nine minutes through Anthony Stokes. But for once Celtic's form deserted them and a 38th minute equaliser from Russell Anderson and an angled drive by Peter Pawlett five minutes into the second half gave the Dons victory. It was their first win at Celtic since they beat them in a Scottish Cup quarter-final six years ago. Celtic, who have won the Scottish Cup a record 36 times, had not conceded a goal at home for 12 matches and had not lost a domestic match since September when Morton beat them in the League Cup. Celtic, champions for the last two seasons, have won 21 and drawn three of their 24 Premier League matches and lead the standings by 21 points from Aberdeen, who are second.
