It goes from bad to worse news for the Stormers, with confirmation that Ruan Ackermann's card has been upgraded to a red card.

Not sure he can have many complaints, high degree of danger and no mitigation.

It's two yellow cards in quick succession for the Stormers...

Hollie Davidson immediately blows her whistle and Salmaan Moerat is sent to the sin bin for an unnatural move.

Moerat's foot knocks the ball loose as Jamison Gibson-Park picks the ball up from the back of a ruck.

Some really tired bodies out on the pitch now, with quite a few players receiving some attention.

This sin-bin period has been managed brilliantly by the South African side, with them closing the point deficit and applying real pressure to Leinster.

Everything is starting to fall their way. The game is far from over!

It looks like Jamison Gibson-Park will continue for now, but I wouldn't be surprised if he gets substituted soon.

Jamison Gibson-Park is on his knees getting medical attention.

That would be a huge loss for Leinster, as his rugby IQ is next level.

He's had a brilliant game so far.

Oh my word! A massive carry from Imad Khan brings the Stormers to just outside Leinster's 22 but Hugo Keenan brings him down.

What a tackle. That was definitely try-saving!

Beautiful foot work from Max Deegan and Sam Prendergast there.
