With GB currently two players down, they really are going to have to try and keep the ball and play simple.

Ooohhh! Helen Richardson-Walsh dives at the back post, think Gazza at Euro 96, similarly not getting a touch.

Ball comes in, shot away. Black bodies diving everywhere, but another foot gives GB another chance...

L Higgins: @TeamGB's #Hockey team are the very definition of steel and a desire to give every ounce for the cause!

Southendman: This is turning into a episode of #Casualty

Medical staff as busy as the players at the moment. GB might need to book a hospital ward. Still, they have a penalty corner...

Georgie Twigg is helped to her feet to applause. She's leaving the field.

I've just seen a replay, the ball deflected into her chin from no distance. Horrible. No blood, though.

That's like taking a Mitchell Johnson bumper in the face. Without a helmet.

The GB players, used to seeing injuries like this, huddle away from the prone Twigg. Alex Danson even has a smile. All in a day's work.

My word. Georgie Twigg has taken a horrible blow here. No chance to get away from the ball, she's hit square in the face.

Brutal, brutal stuff.

There is no reason for GB to do anything other than the simple game.

They do all the strength and conditioning and running work for moments like this.

Lily Owsley's running provides relief for Great Britain. Still the bulk of the noise is of a British persuasion. Long effort from GB, sliding wide.

Claret coming from the head of Crista Cullen.

"Great tackle Crista," shouts someone as she runs down the tunnel.

This is by far and away the most vocal the British fans have been during any hockey match at this Games.

Cullen has gone for stitches. Hard as. Bottles of water are poured on the affected area. Hi-tech solutions to brutal problems.

It is one of those unfortunate injuries. She might have taken a knee to the head.

I haven't seen a replay, which also suggests something pretty gruesome. GB's Cullen has spilled blood for the cause. They call for a bucket of water to clear the field. Cullen walks off with ice held to her head.

This doesn't look good. Nasty collision. Crista Cullen is down.

Georgie Twigg jumps up and down, ready to join the fray. NZ come down the right, but are snuffed out. Red shirts behind the ball.

Kate Richardson-Walsh has a jaw like Lennox Lewis in his prime. Fans are in agreement that she's just taken one clean in the face.

After defending a penalty corner she lashes her helmet into the net. Body language that screams defiance.

If your impression of hockey was a very pleasant runaround at a posh school, think again. This is brutal stuff. Bodies clattering, sticks meeting flesh, limbs on the line. Blood and thunder.
