Mikey Johnston gets a shot on target for Celtic, but it's easy meat for Jak Alnwick.

Aberdeen are pressing late on. Ash Taylor meets a free-kicks but puts it into the hands of the goalkeeper. Then Bruce Anderson gets to Tommie Hoban's cross but steers the header wide of the post.

St Johnstone look like pulling off their own Great Escape this afternoon.

Remember, the visitors were 2-0 down at the interval.

Still Celtic keep coming, and still St Mirren are largely untroubled.

Ryan Christie's volley from the edge of the box is never likely to trouble Jak Alnwick, who has barely had a save to make.

With the clock ticking down, Aberdeen are heading for their fourth goalless draw in eight games, and their second in a row, but Matty Kennedy should really have burst the net after a nice flick from Ryan Hedges.

But the former St Johnstone man tries to chip the goalkeeper and puts it well over the bar.

A big shout for a penalty for United.

Left-back Josh Doig looks to have controlled the ball with his arm as spins away from Lawrence Shankland before clearing.

However, referee Gavin Duncan is not interested.

Aberdeen players are surrounding the referee demanding action is taken against Nicky Devlin after Matty Kennedy is scythed down.

But Steven McLean is having none of it, asking the Dons players to calm down, and the game begins with a bounce ball rather than a free-kick.

St Mirren keeper Jak Alnwick is a relieved man as he sends a goal kick straight to Celtic's Tom Rogic 30 yards out, but the hosts fail to capitalise.

Celtic are having plenty of possession but struggling to do anything with it as St Mirren protect their lead without too much stress.

Can the Paisley men hold on for a famous win?

Ross McCrorie burrows his way through the Livi defence, taking the ball off Efe Ambrose, and rifles a shot at goal which is well saved. Aberdeen's first chance of the second half.

David Turnbull's strike deflects off Jamie McGrath and flies wide.

The resulting Celtic corner finds Shane Duffy, but the defender can't make amends for his earlier error as his header sails over the bar.

United threaten on the break and Lawrence Shankland has a sight at goal.

However, the misfiring Scotland striker's drive takes a deflection off defender Darren McGregor and, just when it looks like deceiving Ofir Marciano, the goalkeeper stretches out a leg to clear.
