And now Hull KR take the lead at Salford! After a long spell of Salford pressure, Josh Drinkwater gets the opening score for the visitors.

Like Huddersfield, a win for Hull KR will see them safe.

Early Huddersfield nerves might have been settled a little bit with a try in the left corner for Louis Senior.

The Giants will be safe with a win.

Blood, and, thunder.

Huge up and under inside the opening two minutes and Wakey full-back Morgan Escare takes it under no pressure. You just get the feeling that it's going to be about defence tonight.

Wakefield end their set of six in the same fashion, London's Alex Walker takes the bomb and wins a penalty for his side as he's hit late after off-loading the ball.

Wow, this is intense already.

We're under way at all five grounds. The closest we've got to a 'Million Pound Game' is Wakefield v London and it started five minutes late at Belle Vue.

Just for the avoidance of doubt, if London lose they are relegated from Super League.

If London win, Wakefield, Huddersfield or Hull KR will be playing in the Championship next season.

Enjoy everyone.

Warrington and Salford are battling it out for third place in Super League, and therefore an easier route through the play-offs.

The Wire are just about in pole position, but could win and still be overhauled by the Red Devils because of their relatively close points differences.

Leeds are safe from the drop and can't reach the play-offs, so in that sense they have relatively little to play for.

However, they will be hoping to send two club legends - Jamie Jones-Buchanan and Carl Ablett - into retirement with a victory.

I'd be focusing on the performance and the start, particularly the first five or six sets for both teams, which are massively important.

If Wakefield get a good start, I'm not sure London have the arsenal to get back into the game over a long period of time.

As recently as six years ago, Huddersfield were winning the League Leaders' Shield and were within 80 minutes of a Grand Final. Tonight, their status in the top flight is at stake.

"The table doesn't lie, we deserve to be where we are," said Giants and England winger Jermaine McGillvary before the visit of Catalans.

"I'm not sulking because I think we deserve to be higher, we have been shocking all year. The season has been an absolute write-off regardless of what happens.

"Everyone is hurting, not just the players but staff, fans and everyone involved. It's all our, the playing staff's, fault.

"There are three other teams in the situation as well and it is still in our own hands. If we get a win against Catalans we stay up. It is all down to us."

Hull KR missed the chance to secure survival last week, with their loss to London prolonging the relegation battle into what could be a dramatic finale tonight.

"We understand the ramifications of this week, as we understood the ramifications of last week," head coach Tony Smith told BBC Radio Humberside.

"It is not being taken lightly but we are not going to sit around and worry about things when we have to take them into our own hands.

"It (relegation) can hurt, and hurt clubs for many years. We are determined to get things great here over the next few years and we will regardless of which competition, but we certainly want to be in Super League and have that as our starting position."

A social media blackout has been imposed on Wakefield's players as head coach Chris Chester tries to get them to focus on the game and not its consequences.

"The players know the enormity of what is at stake," he told BBC Radio Leeds. "The social media blackout is to take pressure away from them and have them solely focused on getting a result.

"It (relegation) has not been discussed. They don't need me ramming it down their throats. The one thing the guys will be on Friday is ready."

London Broncos know all about winning big games. They beat Toronto in Canada last year to win promotion via the Million Pound Game, and have delivered some eye-catching victories against St Helens, Wigan and Leeds in Super League this season - when many expected them to be certs for relegation.

Can they pull it out of the fire one more time to survive in Super League?

"There is less money in the Championship than there was before, so this game is worth more than a million," owner David Hughes told BBC Radio 5 Live's Rugby League podcast.

"It would be a massive achievement to stay in Super League. We are a side that averages 1,500 to 2,000 people and you need to get 10,000 to a Super League game to break even, so you can work out what we lose and what we can't afford to pay on the squad."

There's a spirit among the squad and I got that sense early on. Then they won three wins in the first six games - everyone started believing a bit more.

I know people have commented on the crowds building slowly but there is a sense of something happening. If the sport genuinely wants to look at expanding and introducing teams from elsewhere, then London is one of those areas that needs to grow.

"The more experienced players we can get on the field, the better" were the words of Wakefield coach Chris Chester in the build-up and he's been true to his word.

Though expected, the headline inclusion is centre Ryan Atkins, who rejoined the club last month, nine years after his original stint at Belle Vue.

For London, unsurprisingly Danny Ward goes with the same starting team that won at Hull KR last week to take us to this final round showdown.

There is one alteration among the interchanges though, as Will Lovell replaces Guy Armitage.

Wakefield: Escare; Jones-Bishop, Lyne, Atkins, Hampshire; Miller, Brough; Kopczak, Randell, Tangata, Kirmond, Tanginoa, Crowther.

Interchanges: Wood, Green, King, Arundel.

London Broncos: Walker; Dixon, Morgan, Kear, Williams; Abdull, Lamb; Battye, Cunningham, Butler, Gee, Pitts, Yates.

Interchanges: Fozard, Mason, Hindmarsh, Lovell.

Speaking of which...

Defending champions Wigan showed more evidence of the great form they're in going into the play-offs, and secured second place in Super League with victory over Castleford yesterday.

It's not just at the bottom of the table where there's something to be decided tonight...

Castleford's defeat by Wigan on Thursday left the door open for Hull FC to claim the fifth and final play-off spot in Super League.

The Black and Whites will finish above the Tigers if they beat runaway leaders St Helens.

You can feel the excitement and the anxiety around the stadium. The Hull KR fans are probably feeling the pressure the most because they're coming up against the form team in Super League.

I think it'll be London, but who on earth would back against them?!

They weren't favourites to beat Toronto in the Million Pound Game last year and they won there. They had to go to Hull KR last week and win, and they did.

To win 10 games this season and be in this position - they have nothing to lose.

This is how the bottom of the table looks going into tonight's final round of regular-season fixtures...

The scenario for London is straightforward. Lose to Wakefield and they'll be relegated, win and they'll stay up - leaving the other three sides in a very precarious position.

Even if Wakefield are beaten by the Broncos, both Huddersfield AND Hull KR would need to win to send Trinity down (barring an unlikely swing in points difference).

Rovers and the Giants will be safe if they win, regardless of the result at Belle Vue, but defeats for either would leave them relying on scores from elsewhere to survive.
