Wasps wing Christian Wade has taken a knock to the bonce and is heading off.

The hosts are camped on the Sale try-line at the Ricoh.

There's a few handbags as a number of players share some pleasantries but it comes to nothing and we head back to a penalty given to the hosts. 

Saracens are in possession and are rumbling forwards with purpose. Quick hands releases the ball out with to Mike Ellery but he runs out of space and they head back in field. This is looking very promising from the hosts... 

Schalk Brits is penalised for not rolling away and immediately Gloucester signal to the posts. James Hook lines up the penalty and the Cherry and Whites take valuable points while still down to 14 men.

Sale are punished for offside inside their own 22 and the ever-reliable boot of Jimmy Gopperth slots an easy three points for Wasps.

The lead is up to seven as they approach the midway point of the first half at the Ricoh.

Gloucester put boot to ball again and Chris Wyles makes another error trying to collect the high ball. Time for a Gloucester scrum and an attacking platform for the visitors to work off. 

Saracens contest the breakdown with vigour and put Gloucester under great pressure. We're just heading to the TMO to check that Jim Hamilton's clear out is legal. It's deemed a penalty only and Gloucester look to make ground. 

Wasps are penalised at the breakdown and AJ MacGinty steps up and slots over the three points on eight minutes.

Good start for the visitors.

Again Alex Lozowski makes no mistake with a penalty kick at goal and Saracens open up a four point advantage.

Injured Wasps and England flanker and BBC Sport columnist James Haskell appears to be enjoying taking a few snaps at the Ricoh Arena.

Not much action on the pitch in the opening five minutes so far though.

John Afoa receives a yellow card as once again he's penalised at the scrummage and the question now is what will Saracens be able to do with a man advantage for ten minutes? 

Gloucester are enjoying a spot of possession but once again Saracens' captain Brad Barritt is on hand to deliver the tackle that dislodges the ball and forces the knock-on. 

It's another mighty shove from Saracens as their forwards are starting to exert themselves. Alex Lozowski lines up the penalty at goal and nails it through the middle of the uprights. 

AJ MacGinty gets things under way for Sale at the Ricoh Arena.

What can third-placed Wasps do with Premiership leaders Saracens involved in a tight battle with Gloucester at the moment?

Although it looks as though Sarries have just edged ahead...

It's another big penalty off the scrum for Saracens and that gives them the opportunity to clear their lines and have a spot of breathing space. 

Gloucester have got their tails up and are sticking with their game plan of hard carries off the first phase. That's before a jink through off the boot finds Charlie Sharples but he can't quite keep possession as Brad Barritt makes a vital tackle.

The pressure remains on the hosts as the two teams set up the scrum five metres out.
