That's just about it from us today, on what could prove to be a pivotal day at both ends of the Premiership.

We're back tomorrow from 14:30 BST to see if Bristol can do the unthinkable - beat leaders Wasps to preserve their Premiership status.

There's also coverage of Northampton's game with champions Saracens.

In the meantime, catch up with today's three Premiership games in the rugby union section of the BBC Sport website.

Thanks for your company.

So this is how the Premiership looks after today's results...

Leicester have opened up a four-point gap between themselves and fifth-placed Bath.

Gloucester are within one point of the top six, while Sale remain 10th in the table.

At the bottom, Worcester's win leaves Bristol 12 points adrift at the foot of the Premiership and they will be relegated if they lose to Wasps on Sunday.

All over at Welford Road. Huge result for Leicester, made all the more important because of Bath's slip up at Worcester.

Could this be the defining moment in the battle for the top four?

All over at Sixways!

Worcester take a giant step closer to Premiership survival.

With Leicester beating Newcastle handsomely, Bath's hopes of the top four have been severely dented.

With the last kick of the game, Billy Burns slots a penalty through the posts.

Sale, having done so well today, only come away with one point.

George Ford kicks a fourth penalty for Bath, who reduce their deficit to six points.

Some hope with two minutes to play?

Game put to bed.

Ben Youngs breaks through a tackle on the right-hand side and runs in from around 30 metres to give Leicester the bonus point after evading another Newcastle defender's efforts on the line. 

Meanwhile, Sale's AJ MacGinty has just scored a penalty to make it Gloucester 36 Sharks 30.

What a wonderful, wonderful move from Gloucester to potentially win this match. Tom Marshall shows a blistering turn of speed, lays off to Ben Vellacott and the Billy Twelvetress does the rest.

Excellent conversion from Billy Burns adds the extra two.

Worcester are almost home and hosed!

The win that will take them to the brink of Premiership safety is almost secure, courtesy of a try scored by former Bath lock Will Spencer.

Ryan Mills kicks the conversion to establish a nine-point lead.

Finally we have a bit of play and Newcastle manage to scramble it clear. They don't want to go out with a whimper it seems.

Scrum after scrum after scrum after scrum. It's like Groundhog Day at Welford Road as Leicester keep turning the proverbial screw against Newcastle.

They can't get out of the succession of scrums though at the moment. Yellow card coming for Newcastle?

These were the scenes after Wynand Olivier's second-half try that put Worcester in front.

A win will leave bottom club Bristol an almost impossible task to stay in the Premiership.

Bath are back to within two points at Sixways with 13 minutes to play. George Ford kicks his third penalty of the afternoon.

With Leicester winning easily against Newcastle, a victory is critical for Bath's top-four hopes.

England coach Eddie Jones is watching an eventful game at Kingsholm, where Sale are still just ahead against Gloucester with about 15 minutes to play.

AJ MacGinty has added another penalty and the Sharks lead by five points, but they've lost Ross Harrison to the sin bin for 10 minutes.

It's an easy conversion for Freddie Burns.

And, after all the handbags, the referee gives a lesser-spotted penalty restart to Newcastle. Anyone know the last time that happened in the Premiership?

Worcester almost have a third try! But Taulupe Faletau saves the day for Bath, racing back to beat Chris Pennell to a kick through and touch down ahead of the Warriors' full-back.
