There's a lot to process here, but it could well be a penalty try for Leicester.

Darcy Graham, running backwards towards his own posts, knocks on, and Jamie Ritchie, who was offside, prevents the Tigers scoring by playing the ball.

He's dragged over his own line, and Leicester are setting up for the scrum, but surely the officials will look at this?

Jasper Wiese is penalised at the breakdown, and for once, Emiliano Boffelli misses his mark off the tee - the wind pushing the ball onto the left upright.

Could that miss prove to be crucial?

You could hear Jasper Wiese smash his way through Jamie Ritchie from the stands in the build-up to the try.

He'd only been on the field since half-time but he showed tremendous power and then nimble footwork to dot down.

Tigers fans finally find their voices in the second half.

He doesn't miss from there doesn't the Argentine.

Edinburgh lead for the first time.

Duhan van der Merwe makes his second carry of the game off the back of that scrum, and Leicester are pinged for offside.

Emiliano Boffelli calls for his kicking tee...

Leicester don't form their lineout quickly enough after a monstrous clearance kick from Blair Kinghorn.

Edinburgh opt for a scrum from the free-kick and will want to turn the screw.

Brilliant defence from Dan Cole.

Edinburgh were knocking Leicester back with every carry, but the veteran prop gets over the ball and wins the Tigers a crucial penalty.

They look to go long over everyone, and eventually Jack van Poortvliet clears for the hosts.

Edinburgh come again though through Bill Mata and co...

Now Henry Prygos shows-and-goes, and slips away from Dan Cole's attempted tackle.

He puts boot to ball - Freddie Steward ushers the ball into touch, and Leicester's line-out will be put to the test here.

Edinburgh have come flying out of the blocks at the start of this second half.

Parity is restored and it's game on.

Edinburgh are held up over the line, but had a penalty advantage to fall back on.

Emiliano Boffelli makes no mistake from bang in front, and we're all square.

Jasper Wiese has come on for Olly Cracknell for this second half.

Edinburgh have started the half brightly, and are deep into Leicester territory after a big Jamie Ritchie carry...

We are back under way at Welford Road.

Some tries would be nice please fellas.

Duhan van der Merwe has looked cold and miserable out on his wing so far.

Mike Blair might well be telling the big man to come infield, get involved, and warm himself up a bit in the second half.

A man of his heft could be pivotal in conditions like these.

It's like a game that belongs in 1973. Balls on the ground, mistakes, the conditions look bad, the pitch looks bad, everything looks bad.

It's a shame, because I was looking forward to this game. Line-outs are a mess, and scrums are a mess.

It will come down to who makes the fewest mistakes.

Just when it looks like Edinburgh had unlocked the Tigers defence, Darcy Graham can't quite gather the ball from behind him, and it's hacked clear.

Emiliano Boffelli is alert to the danger and sweeps back to prevent a breakaway try for the hosts.

And with that, the players head for the sheds. Fair to say it hasn't been a classic.

The bounce of the ball is favourable for Henry Prygos and Edinburgh - he releases Mark Bennett who barges his way over the gain-line and into Leicester's 22.

The home defence has been rock-solid so far, but they need one last push before half-time.

The rain may have begun to fade, but it's still incredibly slippy out there.

One pass too many from Edinburgh - the ball goes to ground, which allows Leicester to clear.

As the rain begins to fade away, the intensity from both sides picks up.

Handre Pollard throws a no-look pass deep inside his own half and Blair Kinghorn steps his way out of trouble in midfield.

We'll have more of this in the second half please.
