Although Celtic are down to 10 men, you just don't know what way this game is going to go

Another corner to Celtic. This time it's headed clear and Paulo Bernardo can only reply with a weak shot.

Adam Idah is all alone up front for Celtic and does well to win a corner, which is headed narrowly over from Daizen Maeda.

The home side are slowly working their way into this game, enjoying a spell of sustained pressure.

Hearts' Alan Forrest throws himself at a diving header but can only skew the ball high and wide.

It was wonderful play, all the way from the back, played out brilliantly. Maeda drives forward, but Idah shouldn't have been offside. Just hold your run.

Matt O'Riley slams an angled shot in off the post but everyone in the ground knew Adam Idah was offside when he gathered the ball in the build up...

It's a huge task now for Celtic. Ten men in a volatile Tynecastle atmosphere.

The fans are up for it and Celtic have to stand up and really be counted.

I don't think there's any doubt at all. The boot was high, it probably just caught Alex Cochrane in the face. The problem for Yang is he sees Cochrane come towards him and he still puts his foot up.

Was it dangerous? Absolutely. In this day and age, it's the right call.

Oh my. Yang Hyun-Jun is off.

Harsh is the first thought but it does get worse every time you see a replay.

Not sure there was any significant contact and there's certainly no malice, but that foot is very high and it has been seen as endangering an opponent.

Hang on, referee Don Robertson is off to the monitor to reassess that high challenge from Yang.

A very high boot from Yang Hyun-Jun appears to graze Alex Cochrane on the head.

The Hearts defender is okay to continue.

Zander Clark saves with his feet as Adam Idah goes down the middle.

The Celtic striker, who scored two penalties at Easter Road recently, has not caught that one cleanly.

Yang Hyun-Jun is upended in a collision with Alex Cochrane.

It's clumsy, but a bit on the soft side.

VAR not asking for a second look.

A chance for Alex Cochrane to have a pop as the ball breaks his way near the edge of the box but the Hearts full-back swipes an ugly shot way wide.

Both sets of fans voice their disapproval as referee Don Robertson tries to let the game flow, but play is eventually halted as Matt O'Riley catches Jorge Grant on the shin as he stretches to win the ball.

The ball bobbles around in the Celtic penalty area and it looks like it might fall for Lawrence Shankland before goalkeeper Joe Hart snaffles it up.

Yang Hyun-Jun was very lively in the midweek demolition of Dundee and the Celtic winger shows nice feet to slip a pass into Matt O'Riley, but Stephen Kingsley gets across to block the cross near the byeline.

A peep of the whistle from referee Don Robertson and away we go.

Celtic have had a huge boost. It's amazing what a week can do.

Idah gives them a different option and Yang had a really good game during the week, just get crosses into the box.
