Both sides are back onto the field at Sixways and it's a huge 40 minutes. 

Will Worcester pull off a shock or will the reigning Premiership champions run away with it? 

Let's find out!

In the past few minutes, it has been confirmed that George North will not start for Wales against England after failing to recover from his leg injury.

There is more on that news, with build-up to this evening's game from Cardiff, plus the conclusion of Italy v Ireland, live here.

Slightly behind the play at Sixways, the first half ends at Welford Road with Leicester Tigers deservedly ahead.

The hosts have been dominant at the breakdown and extended their lead just before half-time thanks to Owen Williams' drop goal.

Worcester director of rugby Gary Gold asked for his side to show plenty of 'fight' in this game and so far they're doing so. 

Of course there's 40 minutes to go against the reigning domestic and European champions but it's been a productive first half from the hosts. 

It's been a productive opening forty minutes from the hosts, they pushed themselves into a 9-0 lead thanks to the boot of Ryan Mills 

Chris Ashton got Saracens off the mark four minutes from the break before Mills added one further penalty. 

Big second half on the way!

After conceding a try a clean and efficient strike off the tee is exactly what Worcester needed.

Leicester remain in control at Welford Road.

The hosts have seen a third try disallowed for an obstruction, after Tigers thought they have extended their lead.

Gloucester are second best, so far.

Saracens knock-on from the high ball and it's another opportunity for the two forward packs to clash. 

Schalk Brits takes it against the head and the visitors are looking to get some phases together and finally mount a true attack of their own.

Ryan Mills adds another three points to his tally for the afternoon and with 27 minutes played the hosts have started strongly indeed. 

Time for the first TMO intervention of the afternoon after Mike Ellery clashes late with Francois Hougaard.

The South African scrum-half has just come back from injury so there are a few concerns for the home fans but he seems okay and the decision is that Ellery will send ten minutes off the field. 

Worcester have their tails up and are looking composed during this opening quarter of the game.

Saracens are pinged for not releasing and Ryan Mills steps up and nails the kick. 

Worcester are keeping the possession well and asking questions of Saracens' defence. 

They're patiently going through the phases but Matt Gallagher soars into the air and takes the crossfield kick from Ryan Mills to clear their lines.  

Meanwhile, the two sides have traded penalties at Welford Road to see Tigers 10-3 up against Gloucester.

Ryan Mills gets an opportunity to make amends for his first miss and he does so with ease. 

The hosts have started with great intensity and thoroughly deserve their early lead.

Leicester make a great start against Gloucester, as Luke Hamilton crosses for an excellent early try after good work by Jack Roberts and Freddie Burns adds the conversion.
