Northampton 14-13 Leicester
Freddie Burns punishes Northampton with another cleanly-struck kick and the visitors are just one point behind now.
Northampton 14-10 Leicester
Northampton concede a penalty in Leicester's half and lose territory. They exchange long kicks downfield and, eventually, from a Tigers scrum just inside the Saints half, they concede another soft penalty, and Leicester might aim for another three points from this...
Harlequins 10-7 Newcastle
Harlequins take the lead at home against Newcastle, with Rob Buchanan finishing a great counter attack.
Tim Visser came up the loose ball, with Mathew Luamanu putting the hooker over.
Elsewhere, the strong wind down at Sandy Park seems to be working in Sale's favour as AJ MacGinty lands his second penalty of the day to put them 6-0 up against Exeter.
Northampton 14-10 Leicester
Freddie Burns opts for the tee from 27m and his kick does the business, bringing Tigers back within four points.
Northampton 14-7 Leicester
Saints remain seven points up. Adam Thompstone went for the line for the visitors but he momentarily lost control in the tackle and the ball spilled forward by a fraction before being regathered.
This is proper end-to-end stuff though.
Northampton 14-7 Leicester
Leicester might have the game's fourth try... The referee is going upstairs to have a look.
Northampton 14-7 Leicester
Louis Picamoles, take a bow. The France number eight does very well indeed down the right and his offload feeds full-back Ahsee Tuala for the game's third try inside 10 minutes.
Stephen Myler's kick restores the hosts' seven-point lead.
Exeter 0-3 Sale; Harlequins 0-7 Newcastle
An update from around the grounds, and we turn attention to Sandy Park first where Sale have landed the first points of the game against Exeter.
AJ MacGinty slots a superb penalty which had plenty of wind assistance.
Meanwhile, Newcastle continue to lead Harlequins 7-0 a The Stoop.
Northampton 12-7 Leicester
Well, this is a quiet game...
Northampton 7-7 Leicester
After conceding, Leicester go on the attack and put pressure on for 12, 13 phases.
Eventually, Ben Youngs pops it up for Adam Thompstone to burst through and he has acres of space to leap over under the posts.
Freddie Burns converts to make it 7-7.
Harlequins 0-7 Newcastle
Newcastle open the scoring at the Stoop with Tane Takulua touching down after some fine work from Mark Wilson, Nili Latu and Alex Tait.
Northampton 7-5 Leicester
... But Tigers respond almost immediately!
Northampton 7-0 Leicester
It is a poor error from Tigers full-back Telusa Veainu, perhaps struggling to see the ball in the bright sunshine, as he fails to gather Stephen Myler's high kick and Saint's Nafi Tuitavake pounces to cross for the early try.
Myler easily adds the extras from directly under the posts.

Northampton v Leicester (15:00 GMT)
This afternoon's derby match will be the last for Leicester boss Aaron Mauger, who has been overlooked for the head coach role in favour of ex-Tigers coach Matt O'Connor.
The 36-year-old former All Black has said he is "devastated" that Tigers chose not to appoint him, having been in interim charge of the club since Richard Cockerill was sacked in January.
"The club have made that decision in the best interests of the club, and what they believe going forward, so I have to respect that and move on," he added to BBC Leicester Sport.
