And a red card for County captain Jack Baldwin.

St Mirren boss Stephen Robinson confirms Keanu Baccus and Mark O'Hara were enforced changes due to international duty and injury, respectively.

"Mark pulled up in the last few minutes of training yesterday, which is a blow, while Keanu we were prepared for," he tells BBC Scotland.

"Caolan [Boyd-Munce] comes in and he's been fairly good this season while Ryan [Flynn] will not let us down. Toyosi's pace, too, can cause problems."

On today's game against Celtic, the St Mirren manager adds: "We have showed we can score goals against them, but we have switched off on occasions defensively and made it hard for ourselves.

"It's the mental side of the game for us today, we have to be at 100% for the 90+ minutes. Technically we are good enough and physically we are definitely good enough in terms of fitness."

An incredible passage of play at Easter Road.

Teenager Rudi Molotnikov had just come on the pitch and jinked his way into the Motherwell box before his shot was blocked.

Jair Tavares swung in a beauty of a cross which Dylan Vente just misses.

It breaks to Lewis Stevenson on the edge of the box and his shot crashes off the bar.

Motherwell keeper Liam Kelly may have got a touch on that one.

Stephen Robinson has made three changes from the sensational win at Pittodrie on Saturday.

Keanu Baccus is off on international duty for Australia, while fellow midfielder Mark O'Hara drops out of the squad completely and Lewis Jamieson moves on to the bench.

Ryan Flynn and Caolan Boyd-Munce will have their hands full in midfield, while Toyosi Olusanya will support Mikael Mandron and Greg Kiltie in the forward areas.

Defender Maik Nawrocki makes his first Celtic start since 13 August.
