Billy Searle kicks deep into Saints territory.

Joe Heyes drives the Tigers forward after the visitors claim the line-out confidently.

Breathless stuff already with just 10 minutes gone.

We said it was going to be 100mph and it's certainly been that but that try is massive.

First entry into the 22 and come away with a try.

Leicester think they're over.....

What a start for the Saints!

I thought Leicester looked short on this right-hand side for a good couple of phases. Northampton just kept the ball in and Tom Litchfield, who I think has been Northampton's best player all season, has proven why.

How will Leicester respond?

Well they have a scrum five metres out for a Northampton knock on.

Here we go....

We are under way in the first of the two Prem semi-finals that are happening this weekend. The atmosphere is absolutely superb inside Franklin's Gardens.

Hang on to your hats, folks!

I think Northampton are favourites, they've been my best team all year in the Premiership for sure.

Maybe they've had a weak couple of weeks but they've has come changes, tried to rest some bodies and everybody is back fit tonight a part from a couple of props which could be the most vital people they would have liked to be on.

It's one of those nights. Derby day, Northampton, semi-final and it sounds a bit cheesy but there is literally no tomorrow. It's all about today, it is the big game, they can't focus on anything ahead of this.

You feel that over the past couple of weeks this is what they've been building for. The performances haven't been the best from the Tigers and Northampton, but they've got themselves into the knockout phases and you feel they've had one eye on this semi-final for a while now.

You need individuals to step up and it needs to be a proper team performance. You need some superstars today, someone to grab the game by the scruff of the neck and make a name for themselves.

You can hear more on the Tigers team news - including those inclusions of Messrs Seale and Steward - in the Leicester Tigers Rugby Show which is out now.

As previously mentioned, both Saints and Tigers have beaten each other twice this season.

All four matches ended in home wins, and with the fifth and final chapter set to be written tonight, Northampton will be buoyed on by their supporters at a sold out Franklin's Gardens.

86% of all teams to host a semi-final over the years have gone on to earn a place in the Grand Final.

Can Leicester change that and dash the hopes of their rivals from less than 30 miles away?

This shows the strength and depth on the Saints squad.

The fact that they can replace their starting team with absolutely class replacements and I think that is something that's hugely exciting that they're willing to put in more than an 80 minute performance if that's what it takes.

Leicester duo Billy Searle and Freddie Steward have both returned from injury in the nick of time and start tonight's semi-final.

Fly-half Searle last turned out for the Tigers in April but he has now overcome a hamstring problem and comes in for James O'Connor who had to be replaced at half-time against Bath last Saturday due to injury.

While England international Steward starts at full-back following successful surgery on his thumb, taking the place of George Pearson, and there is also a return to the side for Ollie Hassell-Collins on the wing.

Leicester Tigers: Steward; Radwan, Wand, Bailey, Hassell-Collins; Searle, Van Poortvliet; Smith, Blamire, Heyes; Martin, Chessum, Liebenberg, Reffell, Moro.

Replacements: Clare, Van der Flier, Hurd, Henderson, Cracknell, Whiteley, Kata, Perese.

Unsurprisingly, Northampton Saints boss Phil Dowson rolls the changes from the side that narrowly lost to Harlequins last Saturday after his side had already wrapped up a home semi-final.

Only four players from that match remain in the starting XV: Tom Litchfield, Curtis Langdon, Josh Kemeny and Tom Pearson.

Henry Pollock is the number eight and Fin Smith is back at fly-half. The Harlequins-bound George Furbank captains the side at full-back and Emmanuel Iyogun makes his 100th Saints appearance this evening.

Northampton Saints: Furbank; Freeman, Litchfield, Hutchinson, Hendy; Smith, McParland; Iyogun, Langdon, Millar Mills; Coles, Prowse, Kemeny, Pearson, Pollock.

Replacements: Wright, Fischetti, Green, Van Der Mescht, Lockett, Chick, Weimann, Dingwall.

Leicester Tigers director of rugby Geoff Parling has described tonight's semi-final as "very winnable" in the pre-game build up.

Tigers lost back to back games at the end of the regular season campaign to slip to fourth in the table but Parling remains confident of his side's chances.

"I think the game is very winnable. We all know what the stats say but lets go and prove them wrong," Parling told BBC Radio Leicester.

"Derby day - brilliant. There's been a lot of hard work to get into this position. We haven't really spoke about it in a different way to what we would do if it was a normal game against them.

"This is going to be a very different game [to the 41-17 win last month]. We will just take it one moment at a time. It's about which team does the basics best and which team stays clear in the moment."
