Millwall forward Macaulay Langstaff is shoved to the ground as the referee plays the advantage.

Romaine Esse crosses from the right but it hits the side netting.

Ryan Porteous appears to be seeing stars for Watford now.

He was in the wall for a free-kick and takes the full fury of a Marcelino Nunez effort straight to the head.

Porteous goes down with a thump, with the medics rushing on to assess how he is feeling.

He eventually makes his way to the side of the pitch, but is soon cleared to continue.

This is where Sunderland have to concentrate.

They have to get through these 10 minutes and weather the storm.

Middlesbrough have done much of the running in this game but Anthony Patterson hasn't had anything of real note to do in the home goal.

Of Boro's six league goals this season only one has come from open play.

Watford's substitute goalkeeper Jonathan Bond has now come up with a crucial save to keep this fast-starting Norwich out.

He gets a strong hand down to palm an Ante Crnac effort around the post.

Millwall get themselves a free-kick not too far from the six-yard box and in definite shooting range.

George Saville tries to curl one over the wall but it keeps floating up and over the goal. He will be disappointed with that one.

Borja Sainz ended the first half by thumping Norwich back into the lead, and he has started the second half by going close to adding to the advantage.

He drives into the box, then drills an effort into the side netting.

Sunderland spring a counter attack and Patrick Roberts drifts in off his right wing and curls a long range shot wide with his left foot.

Both sets of players have been out for a few minutes now, and finally from the tunnel comes a replacement referee.

Fourth official Daniel Middleton has stepped into the role and gets the match back up and running.

Not even a minute gone in the second-half and QPR already bag themselves a corner. There's been a few of those in this game.

Millwall deal with the immediate pressure with ease as the corner doesn't result in anything but it's clear QPR are eyeing that second.

The half-time team talk must have been very invigorating for the home side. It's been an energetic start.

There appears to be a delay at Carrow Road for the start of the second half.

Word seems to be that referee Anthony Backhouse might be injured and unable to carry on.

It's been a heck of a day of injuries already, with Watford losing goalkeeper Daniel Bachmann and Francisco Sierralta early on.

We're back under way in our two of our early Championship games.

A reminder that all of your League One and Two action is covered here.

Did you expect such a positive start to the season Black Cats fans?

Thumbs up for yes, thumbs down for no.

What a touch from Sainz to get away from Porteous.

What a ball, what a touch, what a finish!

It certainly was great composure from the Norwich striker to give them the lead in first-half added time.

A fascinating, breathless half of football ends with big moments at either ends.

Sunderland wanted a penalty, Middlesbrough should have had an equaliser.

Boro have been more composed and fluid over the piece but they trail to Chris Rigg's goal.

Sunderland have been dangerous on the break and full of youthful exuberance, personified by Rigg in his backheel.

More of the same second half, please.

Borja Sainz's injury-time strike at the end of the first half has put Norwich back ahead against Watford in this absorbing Championship showdown at Carrow Road.

Hard one to call this.

Millwall have had three more shots than the home side but after Duncan Watmore put them in front, they let their guards down and QPR forward Michael Frey was ready to pounce.

Middlesbrough with most of the possession but its Sunderland who have all the goals at half-time.

Boro had a great chance to take an early lead but Tommy Conway's header skimmed the top of the bar.

They were made to pay for that when Chris Rigg put the home side in front with their first real opening when he improvised brilliantly to backheel in from a tight angle.

Thereafter Boro have had most of the ball but the Black Cats have looked dangerous on the break.

Emmanuel Latte Lath had a good chance to level right on half-time but sent his lofted shot over.
