Dundee United boss Peter Houston was left to rue the absence of Jon Daly and Gary Mackay-Steven as his men drew a blank against Ross County.
The visitors extended their unbeaten league run to 40 matches with this 0-0 draw at Tannadice, recording their fifth clean sheet of the campaign so far.
Mackay-Steven missed the match after undergoing surgery while Daly was forced to sit out due to a knee injury.
Houston said: "There's a lot of positives to take.
"Up until the final third we were excellent. What we need to work on now is where we're going to get our goals from.
"We missed the presence of Daly and Gary Mackay-Steven.
"Jon has had dodgy knees over the last number of years. It could be a couple of weeks."
The Scotland assistant boss praised the Staggies for their resilience, adding: "They're getting draws in the SPL because they're working very, very hard as a team. They're getting behind the ball."
