More fans than usual are returning to their seats late for this second half, and for good reason.
The stiff wind is turning colder by the minute, which will make kicking even more difficult as the pressure rises.
I’m not ashamed to admit the hat, scarf and two pairs of gloves are on!
Logovi’i Mulipola
Sale launch an attack through Marland Yarde but Logovi’i Mulipola tackles him on the 22. Referee Tom Foley goes to the TMO and it is deemed an early tackle and Mulipola gets a yellow card.
A spot of admin to update you on with personnel wise… David Denton won’t be back after failing an HIA assessment. Cobus Reinach is back, though, after having a spot of claret cleared up. Northampton have restarted the game.

Former Northampton Saints player and manager on BBC Radio Northampton
Leicester's game management has been so much better than Northampton's but Northampton do have a lifeline with the try just before half-time but Dan Bigger's missed conversion could come back to bite them.
The Tigers will be the happier while Chris Boyd will be livid telling his team your not doing the occasion justice lads.
HT: Northampton 10-20 Leicester
Northampton enjoyed 67% of the possession in that first half but the scoreboard shows that just they haven't made the most of it.
Seven handling errors in comparison to Leicester's two may go some way to explaining that one. Both sides are back out on the field and the second-half is on the way shortly.

Image source, Getty ImagesNeither of these sides have managed back-to-back wins yet this season, and the inconsistency is shown in their play.
Leicester have played the more fluent rugby, with Ben Youngs scoring his first Premiership try since October 2017.
David Ribbans’ score may give Saints momentum but Dan Biggar will need a better second half if they’re to turn this derby around.

Here's what the Saints think about today's weather conditions... they're bang on too.

HT: Northampton 10-20 Leicester
Image source, Rex FeaturesThis is certainly not a picture that Eddie Jones will enjoy looking at, nor England fans, with the autumn internationals fast approaching.
Leicester have managed the less than ideal weather conditions better than their opponents it that first half and an inspired period from Jonah Holmes helped them into a 15-point lead (20-5) as half-time approached.
Yet, with the emotion of the day driving them on Chris Boyd's Saints banged the door down for a key try with the time in red.
