Leicester have been utterly dominant in the first 15 minutes of the second half and they've built up a 16-point lead.

They're on the attack again inside their own half as Ed Slater runs clean through the Quins defence. 

Tigers will be tough to stop from here...

From the defensive line-out, Leicester launch a huge kick downfield and it's a great chase by Tom Brady who puts James Chisholm under pressure and they concede the penalty.

Chilsholm has been Quins' best player so far this afternoon but that wasn't smart play from the number eight.

Harlequins with their first real period of rest-bite in the second half.

They're just about into the Tigers' 22 but there's no real purpose about their play and eventually, their accuracy lets them down.

Leicester have more good field position after Quins concede another penalty.

Brendon O'Connor once again slips through a tackle and Tigers are asking questions here.

But the ball is slow and the referee has his arm out for the advantage.

Leicester don't wait around and Freddie Burns takes three simple points.

Leicester open up the biggest margin of the game as Freddie Burns slots another kick and stretches Tigers' lead to six points.

So nearly the first try. But the referee was having none of it.

Freddie Burns was a metre away from the referee's mark and despite diving over the try-line, he's pulled back and he'll go for the three points.

Leicester have turned the ball over in a crucial position and the Welford Road crowd have found their voice.

Tigers with a real opportunity here for the first score of the game and it's their forwards who will try to drive this ball over the whitewash.

Plenty of room for improvement after the first 40 minutes. I like your optimism Stephen...

And we're back!

A tough, tough afternoon for running rugby but this is a real battle between two heavy weights.

An exciting 40 minutes to come...

Let me know your thoughts on the first half via #bbcrugby on Twitter.

How many tries are you predicting for the second?

Which players, if any, have been exciting so far?

Not a riveting first half but it remains very even at half time.

Leicester with a narrow lead due to three penalties from Freddie Burns and only two for Harlequins' Nick Evans. Not a lot else of note really.

Perhaps the most entertaining feature has been the similarity in the kits severely hampering my commentary efforts.

Harlequins find themselves right back on their own 10-metre line after giving away yet another penalty, but Leicester lose the line-out and Quins escape.

There's definitely room for improvement for both sides at half time.

And Harlequins are attacking without their number 10 Nick Evans at the moment who's down after a heavy tackle by Ellis Genge. A sore one in the ribs there.

Leicester swarm Charlie Matthews to force the turnover and Freddie Burns slots an easy kick to edge Tigers in front.

We've had a mixed bag from him so far when kicking out of hand, but he's been 100% from the tee.

Inevitably, the scrum goes against the attacking side, and Leicester win the free-kick.

This hasn't been exciting rugby so far and it doesn't look like getting much better as the rain begins to pour down at Welford Road.

Harlequins director of rugby John Kingston will be happy with his side's defensive efforts so far.  

And they're into the 13th phase of possession here.

But it's very messy at the breakdown and eventually Quins are awarded the scrum.

Leicester win their own line-out on the Harlequins 22 and their forwards get a march on.

But Quins come up with the ball and Tigers squander a very handy position. Neither side really into their stride yet.

Nick Evans makes it two from two with an easy kick.

A very evenly contested first quarter, particularly at the breakdown.

An interesting moment there. The assistant referee puts his flag up for a Harlequins player in touch, but the game doesn't stop and we carry on. 

Not sure what happened...Quins won't mind though, they win the penalty a few phases down the line and they'll have the chance the even things up.
