Saracens captain Brad Barritt is now writhing around in agony on the pitch.
Mark McCall won't want to lose him after already seeing Owen Farrell trudge off.
But these are the times when leaders need to come to the fore, and Barritt is set to continue - Schalk Brits will return from his sin-binning in a couple minutes.

BBC Sport at TwickenhamWell now...
Are we done and dusted in this one just yet?
Belief among the Chiefs fans has ratcheted up to maximum after that Schalk Brits yellow card and then Gareth Steenson converted try.
The bright sunshine is cranking up the temperature for those in the stands and it's now brewing up to boiling point among those on the pitch.

Owen Farrell is limping and Sarries are on the back foot, but Mako Vunipola and Maro Itoje team up to win their side a penalty - and some time.
Farrell is now replaced by Marcelo Bosch - how big an impact could that make?
Suddenly it's all to play for.

The old campaigner Gareth Steenson goes over after Exeter move to the left of the scrum.
The Irishman also kicks the conversion and the defending champions are nine points behind while Sarries are down to 14 men for another five minutes.

Exeter 3-19 Saracens
Sam Simmonds almost wriggles his way to a score for Exeter but is just about thwarted.
It's desperate stuff from both sides - Simmonds tries again and fails... Dave Ewers looks to finally force his way over.
But no, he's held up by some excellent last-ditch defending.

Here we go... Schalk Brits yellow-carded for collapsing Exeter's driving maul.
The Chiefs are just metres from the Sarries try-line - this is their big chance.

Paul Grayson
Former Lions and England fly-half on BBC Radio 5 liveWhen Saracens get ahead they know how to squeeze.
Exeter have upped the tempo a little bit since Gareth Steenson has come on, he's been carrying the ball close to the line but there's just not that next level of incisiveness about their attack.

Sarries are covering the full width of the pitch in defence and don't look like buckling.
The fans from Devon are making a great level of noise, trying to will their men towards the 22.

Tom Moffatt: It is safe to safe that Alex Lozowski has dominated Henry Slade today! Looks far more comfortable on the big stage.
Criv: Boring boring Sarries eh?
Fair point Criv, surely no-one can accuse Saracens of not playing an exciting brand of rugby here...

Image source, BBC SportSchalk Brits is off the Saracens bench for his last appearance before retirement.
The South African hooker has won five major trophies in nine years, and Sarries seem to be edging closer to a sixth in his time at the club.
He deservedly gets a rousing reception.

Matt Dawson
Former Lions and England scrum-half on BBC Radio 5 liveThere's been no kicking game from Exeter other than the box kick in defence. In attack they have not had it going forward and they are always trying to run it out.

The Sarries captaincy goes to Owen Farrell as Brad Barritt wonders off for a head injury assessment.
The London side put in the scrum and launch another attack, gliding into the Exeter half.
Even the crowd have gone a bit quiet...

Adam Williams
BBC Sport at TwickenhamRob Baxter's response to conceding that third Saracens try is to empty pretty much all of his Exeter bench.
Off goes Joe Simmonds amongst those changes for the experienced head of Gareth Steenson at fly-half.
A telling moment on an afternoon where one set of brothers - the Vunipolas - have put much more of a telling mark on this final than the Simmonds siblings for Exeter.

Exeter ring the changes in response - veteran fly-half Gareth Steenson and club captain Jack Yeandle among those to come on.
They have possession, but making metres is proving difficult as Sarries continue to stand tall.
Try (Wyles)published at 48 mins

What a slick move, and it's Chris Wyles at the end of it once more.
Saracens draw in their prey and then rapidly play the play to the left for the USA wing to provide the finishing touch.
Owen Farrell squints in the Twickenham sun but nails the conversion from out wide - Exeter need the next score badly.

Image source, BBC SportIt is one of those stunningly bright, warm summer days that makes for expansive rugby and a good day out... but it can also be draining.
Water bottles have been topped up with crushed ice to keep the players cool with the temperature at 26C at Twickenham.

We all know Exeter love building the phases and strangling their opponents, but they've not been allowed to do it much today.
They start the half with a 24-phase move but Sarries celebrate in macho style as the ball is turned over.
A psychological win for the leaders.

Both suggest it's a done deal for Saracens but I'm sure there are plenty who'd have something to say about that.
Remember, #bbcrugby is the place to air your views - you've been a tad quiet so far.
