Aberdeen picked up a point from a goalless draw after failing to register a single shot on target in a hard-fought encounter at Livingston.
There was no shortage of effort from both teams but there was a distant lack of goalmouth action.
Livingston finished the game strongly and at least asked questions of Dons goalkeeper Kelle Roos with efforts from Cristian Montano and Ayo Obileye.
There was little for the 4,000-strong Aberdeen fans to get excited about although Johnny Hayes will be kicking himself that he did not at least find the target from a good position at the back post in the early stages of the second period.
Former Livingston captain Nicky Devlin was in the thick of the action during a fiercely competitive start.
Devlin lined up on the right of a three-man defence that included Dons debutant Sloboden Rubezic.
The visitors created the first chance of note in the 14th minute when Duk met Leighton Clarkson’s cross but the forward glanced a header over the bar.
The Lions grew into the game and Mo Sangare got their first shot away in 22 minutes. Montano’s cross was only half cleared and Sangare chested the ball down before swinging a half-volley wide.
It was the home side that created another chance in first-half stoppage time but Jamie Brandon was unable to get a touch on Montano’s cross.
The second period began how the first half ended with both team’s refusing to give an inch.
Aberdeen midfielder Hayes was disappointed not to score after being found at the back post by Clarkson after finding the side netting as he slid in to reach the cross.
At the other end, Montano volleyed well over after Luiyi de Lucas’ cross was flicked on by Joel Nouble.
The Colombian then registered the first shot on target in the 70th minute when he connected with Scott Pittman’s cross.
The Lions were the team finishing strongly and they were asking plenty of questions of the Aberdeen defence by throwing crosses into the area.
Obileye should have done better when he was found unmarked at the back post from Andrew Shinnie’s corner but Roos got down well to the effort.
Duk then sliced an effort well wide with four minutes left after meeting Ester Sokler’s effort in the box.
Livingston sub Bruce Anderson was carried off on a stretcher in stoppage time after a lengthy delay having come off second best in an aerial challenge with Rubezic.
