Match ends, Dundee 1, Partick Thistle 1.
A late Kane Hemming goal gave Dundee a Scottish Premiership point against a Partick Thistle side who had led for most of the match at Dens Park.
Defender Liam Lindsay got his head to Stuart Bannigan's corner to put Thistle in front early on.
Dundee struggled to force their way back to parity and Lindsay had another chance for the visitors.
But Hemmings' shot following Greg Stewart's pass levelled matters with only a few minutes remaining.
Second-bottom Thistle move to within three points of Motherwell, who lost to Inverness Caledonian Thistle, while Dundee are now level on points with sixth-place Hamilton Academical.
Jags goalkeeping coach Paul Gallacher found himself in the starting line-up as Alan Archibald's other two stoppers were unavailable.
But it was at the other end that the first goal came, an inswinging corner from the right seemingly catching out the Dundee defence and Lindsay nodding in from close range.
While it was a neat finish by the 20-year-old, even he looked surprised at the time he had to find the target.
The goal came against the run of play with Gallacher having saved well from Rhys Healey.
However, Thistle did look a different proposition from the side that lost 4-0 at home to Hearts only seven days earlier and Kris Doolan came close to extending their lead.
The striker was allowed a free header but nodded wide and then tried his luck with an overhead kick that was within inches of finding the target.
Another blow for the Dens Park faithful was the loss of Healey with a leg injury. The on-loan Cardiff City player was carried off with Hemmings his replacement.
A mistake by Kostadin Gadzhalov then almost cost his side a second goal. The defender's attempt at a clearance dropped straight at the feet of Doolan but his shot from close range was straight at keeper Scott Bain.
Archibald had set up his team with five players in midfield and were easily outnumbering the opposition, who were booed off the park at half-time.
Loy, Stewart and Hemmings all struggled to find their route to goal as the game followed a similar pattern in the second half.
Thistle were quite content to soak up pressure and hit on the break, Bain tipping over a long-range effort from Gary Fraser.
Lindsay then came within inches of a second goal, his header whistling just past the post.
But Loy and Stewart combined to set up Hemmings to slot home his fifth goal of the campaign.
And both sides came close to finding a winner with Gallacher saving well from Thomas Konrad and Bain keeping out a Ryan Stevenson shot.
