Leigh Griffiths goes straight into the Dundee starting line-up after re-joining the club on loan from Celtic.

The striker's inclusion is one of four changes to James McPake's starting team with Ryan Sweeney, Jordan Marshall and Alex Jakubiak also coming in. Liam Fontaine and Jason Cummings drop to the bench while Paul McMullan and Charlie Adam are not in the squad.

One change for Livingston with Ben Williamson replacing the benched Odin Bailey in midfield.

St Johnstone's winless start in the league continues, but they can take plenty of positives from today's performance.

Celtic boss Ange Postecoglou has made five changes to the side that suffered an Old Firm defeat last time out.

Centre-back Cameron Carter-Vickers and winger Jota are handed debuts, as Albian Ajeti, Greg Taylor and Tom Rogic also come back.

Dropping out the side are Anthony Ralston, Stephen Welsh and the injured Kyogo Furuhashi - plus Odsonne Edouard and Ryan Christie, who have now departed the club.

Greek striker Georgios Giakoumakis doesn't make the matchday squad.

James Tavernier's incredible finish caps Rangers' comeback as they go top of the table.

Michael O'Halloran gave St Johnstone the lead after the break before Kemar Roofe's penalty leveller.

An absolute cracker of of a second half.

St Johnstone have a corner and keeper Zander Clark comes up for it... but there's no repeat of his Ibrox heroics as Rangers clear.

St Mirren: Alnwick, Fraser, McCarthy, Shaughnessy, Millar, Reid, McGrath, Ronan, Tanser, Brophy, Main

Substitutes: Lyness, Finlayson, Tait, Flynn, McAllister, Dennis, Erwin

Dundee Utd: Carson, Smith, Mulgrew, Niskanen, Pawlett, McNulty, Edwards, Butcher, Harkes, McMann, Fuchs

Substitutes: Newman, Sporle, Connolly, Reynolds, Clark, Levitt, Appere

Rangers exploit the wide open spaces to break forward.

John Landstrum's cross for Alfredo Morelos looks a certain goal, only for Zander Clark to make a superb block with his legs.

St Johnstone have centre-back Jamie McCart playing centre forward now, but Rangers are holding firm.

The board goes up - five minutes of added time.

Can Saints find a dramatic equaliser?

Dundee: Legzdins, Kerr, Ashcroft, Sweeney, Marshall, McGhee, Byrne, Anderson, McCowan, Jakubiak Griffiths.

Substitutes: Lawlor, Fontaine, McGowan, McDaid, Panter, Sheridan, Cummings.

Livingston: Stryjek, Devlin, Obileye, Fitzwater, Penrice, Holt, Williamson, SIbbald, Shinnie, Forrest, Anderson.

Substitutes: Barden, Longridge, Lewis, Montano, Jacobs, Bailey, Hamilton.

Vertainen's first touch is an acrobatic effort that flies a yard or two wide.

We're into the final few minutes of normal time.

Finnish striker Eetu Vertainen is on for his St Johnstone debut in place of defender Hayden Muller.

Another forward, Stevie May, then replaces midfielder Ali Crawford.

The hosts going for broke in search of an equaliser.

Motherwell: Kelly, Grimshaw, Mugabi, Ojala, Solholm, McGinley, Slattery, O’Hara, Woolery, Van Veen, Watt.

Substitutes: Fox, Lamie, Maguire, Amaluzor, Donnelly, Goss, Shields.

Aberdeen: Lewis, McCrorie, MacKenzie, Gallacher, Watkins, Brown, Ramirez, Ojo, Ferguson, Ramsay, Longstaff.

St Johnstone break upfield and Reece Devine's shot is heading on target until it takes a slight deflection and flies behind.

Rangers defender Felip Helander then pulls up with what looks like a knee injury and the Swede goes off on a stretcher. Hopefully the damage isn't serious.

Kemar Roofe has the ball in the net, but only after heading it out of home keeper Zander Clark's hands and the goal is rightly ruled out.
