Jeers from the away fans as Forest keeper Carlos Miguel throws the ball straight out of play while trying to launch a counter-attack.

As long as it is 1-0, Luton will believe.

Bryan Mbeumo is warming up. The game needs him.

Luton are having to make their second injury enforced sub of the second half.

Zack Nelson got an accidental whack to the face from Ryan Yates, and after attempting to play on he is unable to continue. Jacob Brown replaces him on the wing.

More danger for the Black Cats as Lewis Koumas is allowed to cut inside and shoot from range. It's deflected just wide.

From the corner, Tom Cannon lashes a shot high, wide and not so handsome.

All a bit too easy for the Potters.

Marcelino Nunez tries his luck from distance and the Norwich midfielder's low strike has Jason Steele scrambling for a moment.

Just wide.

Luton have failed to progress from any of their last five FA Cup ties when playing against opposition from a higher division, since a 1-0 win over Portsmouth in November 2017.

In contrast to the first half, Reading have come out of the blocks with real intent in the second period.

They're pressing well and stopping Burnley from playing out from the back.

The decision to make three changes at half-time was likely pre-planned - as recently injured duo Reece James and Romeo Lavia are two players to go off.

Pedro Neto also comes off as manager Enzo Maresca gives a hint that the Portugal international will be one of his starting wingers on Tuesday against Bournemouth.

Brentford haven't lookd as comfortable as some Premier League sides with making so many changes today. They have really struggled in the final third.

West Brom not giving up yet as Uros Racic flicks the ball up in the box and volleys just wide.

Big opportunity for Stoke!

Lewis Baker meets Tatsuki Seko's cross bang in front of goal, but heads off-target. That should have been 2-0.

Will they come to regret that?

Just what Morecambe want - Jadon Sancho, Marc Cucurella and Malo Gusto are on at the break.

At least Pedro Neto is off, from a Morecambe pov. And at least it isn't Cole Palmer coming on.

Brighton took a bit of time to work their way into the game at Carrow Road. But once they did, they dominated.

Fabian Hurzeler's team had 60% of the possession in the first 45 minutes with 13 shots to Norwich's four.

More good news for the Seagulls is that Georginio Rutter has emerged again at the start of the second half, the changes at the break are for the hosts.

Kellen Fisher and Brad Hills are on for Callum Doyle and Amankwah Forson.

Was this the goal of the day?

We have a change early in the second half - Mohamed Lamine Fanne has picked up a knock in the opening moments, and is replaced in the Luton midfield by Jordan Clark.

Antoine Semenyo replaces Max Aarons at the break for Bournemouth with James Hill going to right-back and David Brooks going deeper into midfield.
