Aberdeen 2 - 2 Inverness CT
Aberdeen came from two behind to draw with a Ross Draper-inspired Inverness Caledonian Thistle but missed the chance to top the Scottish Premiership.
The midfielder, who had returned from injury, out-muscled Paul Quinn and set up Liam Polworth to fire home.
Draper won a penalty after a Quinn challenge the other side of the half-time whistle and Greg Tansey scored.
Niall McGinn fired a reply to inspire a late Aberdeen onslaught that led to a penalty converted by Adam Rooney.
It preserved the Dons' unbeaten run, which now extends to seven games.
But, although Derek McInnes' side drew level on points Scottish Premiership leaders Celtic, the Glasgow side have a better goal difference and go into Sunday's match against third-top Hearts with two games in hand.
