Aberdeen 2-2 Kilmarnock
Aberdeen fought back from two goals down to claim a draw against Kilmarnock at Pittodrie.
The visitors found themselves in front when Paul Heffernan headed Liam Kelly's cross past Jason Brown.
And Killie doubled their lead when Dean Shiels finished well from inside the penalty area on 28 minutes.
But Andrew Considine pulled one back for the Dons before half-time and Youl Mawene headed the hosts level eight minutes into the second half.
New Zealand international Rory Fallon made his Aberdeen debut while goalkeeper Brown deputised for the unavailable David Gonzalez, with Jamie Langfield on the bench for the first time since suffering a brain seizure during the summer.
Algerian striker Mohamed Chalali and youngster Ryan Jack also started for the Dons with Rory McArdle, Scott Vernon and Chris Clark dropping to the bench.
Kilmarnock made two changes from the side that defeated Dunfermline 3-2 last weekend with Garry Hay and Slovenian Leon Panikvar preferred to Rory McKeown and Alex Pursehouse.
And Panikvar made a brave block after eight minutes, when he stopped Fraser Fyvie's acrobatic effort.
However, it was the visitors who broke the deadlock after 15 minutes when Dean Shiels crossed for Heffernan who netted his fifth of the season with a superb diving header.
Kilmarnock doubled their advantage after 28 minutes when Hay surged at the home defence before releasing Shiels who slotted the ball past Brown.
The Dons were appealing for a penalty when Fallon fell under pressure from Gary Harkins but the former Plymouth striker was shown a yellow card for simulation, much to the disgust of the home support.
But they pulled a goal back after 37 minutes when Cammy Bell flapped at Arnason's looping cross and Considine showed great composure to steer the ball into the unguarded net.
Aberdeen made a switch at the break with winger Peter Pawlett introduced at the expense of the ineffective Chalali.
The change gave the hosts fresh impetus and they drew level after 54 minutes when Kilmarnock failed to deal with Kari Arnason's long throw into the box and Mawene nodded the ball home.
The Dons went painfully close to finding a third when Rob Milsom's free-kick was headed on to the crossbar by Fallon after 62 minutes.
Killie reminded the Dons that they were still in the game with Brown called upon to make a smart save to keep out Liam Kelly's rasping drive.
With less than 10 minutes remaining Chris Clark, a second-half substitute for Ryan Jack, flashed a shot wide of the target as the Reds continued their search for a winner.
Kilmarnock substitute Mohamadou Sissoko headed just over the bar in injury time as both sides had to settle for a share of the spoils.
