This is why I love rugby. The crowd have really got behind the momentum change and the atmosphere has really livened up.
Saracens 24-24 Racing 92
Richard Wigglesworth kicks and Sean Maitland picks up the ball. Sarries go right, then left but are still hovering on the 22.

Elliot Daly has been so sparky throughout the game and he has that ability with the boot to pin the opposition back with his pinpoint kicking.
Saracens 24-24 Racing 92
Brice Dulin puts in a clearing kick of his own and it doesn't make much ground. Saracens have a line-out just outside Racing's 22.
All the momentum seems to be with the hosts now.

If Saracens manage to win this with 14 men, it will be a mammoth effort.
Elliot Daly clears to touch and the crowd erupts. The players are looking more up for this now.

Owen Farrell has to be one the fiercest competitors in rugby. He always steps up when you need him most.
He will probably be one of the players who stays and plays in the Championship. It's hard to see him leaving.
Saracens 24-24 Racing 92
A draw would still give Saracens a chance of reaching the quarter-finals as long as they get a four-try bonus point as well. They would have to rely on Toulouse beating Gloucester to guarantee qualification though.

What a fantastic bit of play from Saracens.
We have been waiting for something to light up this arena.
Maro Itoje (Con Owen Farrell)
Sarries are back in it.
Brad Barritt sends a cross-field kick and Duncan Taylor lets it bounce before grabbing hold of it. Maro Itoje ends up with the ball and is over the line.
Owen Farrell gets the conversion from the right touchline and we're back level.
Saracens 17-24 Racing 92
Racing have already qualified for the last eight but they still have something to play for today. A win would give them a home quarter-final.
Sarries have the ball for now though and Owen Farrell sends a kick cross-field, but nobody gathers and it bounces into touch.

Saracens look deflated. The body language of Saracens' players is in stark contrast to Racing's players.
The Saracens players are so experienced that they will be thinking 'this is a game of rugby we need to win' rather than about the problems going on off the pitch.
Teddy Iribaren
Teddy Iribaren goes for the kick. It's massive and he nails it. The lead is up to seven points
Saracens 17-21 Racing 92
They may be resilient, but it's not all going Sarries' way. Sean Maitland is holding on on the floor and Racing 92 get the penalty.
Will they go for goal from the halfway line or head to the corner?
Saracens 17-21 Racing 92
Saracens coach Alex Sanderson gave an insight into the half-time talk on BT Sport:
"Owen Farrell rounded up well by talking about the choices we have to make. We either lie down and roll over or we stand up and rise. The opening stages of this second half indicate we've gone for the latter.
"I am constantly surprised by the backbone and resilience they have."
Saracens 17-21 Racing 92
Finn Russell starts the second half.
Saracens need to turn this around if they're going to reach the quarter-finals. Ben Spencer sends a high kick up and Sarries knock on.
Saracens 17-21 Racing 92
The players are back out on the pitch and the fans are doing their best to get them up for this second half.

I've heard a fan joking about visiting new stadiums next season. There is a lot of research to be done on where Saracens are heading.

Pretty much sums up the end of the second half for Saracens.
