Brilliant block from Alex Robertson in his own goalmouth to deny Amario Cozier-Duberry what might well have been a leveller.

Nathan Trott can only palm away Tommy Conway's low cross from the left at his near post but Robertson threw himself in the way as the ball dropped to the Brighton loanee and his shot cannons away.

A mistake by Zak Sturge leaves space down the Millwall left.

Andrei Coubis gets a cross to the far post where Freddie Draper has time to control but his shot is deflected wide - that was a good chance to make it 2-0 to the visitors.

We are awaiting the first goal at Vicarage Road, but the yellow cards have flowed comparatively freely.

Watford's Iker Bravo and Charlton's Oliver Skipp are the latest players to go into the book, for fouling each other in separate incidents about a minute apart.

Bravo, who has been bright, had just fired a low shot at Arthur Okonkwo in the Addicks goal, which he saved comfortably.

Lincoln are getting more confidence in defence.

At the moment Millwall are just huffing and puffing. There needs to be a bit more quality and the thing is you just know they have it in them.

BIG Cardiff appeal for a penalty as Jack Moylan goes down in a heap at the near post under pressure from Ash Phillips as he tries to latch onto a low cross from the right flank but ref Tom Nield is having none of it.

Phillips might have been in danger of a red card for denying a goalscoring opportunity there too, you'd imagine, and replays seem to suggest he had a handful of Moylan's shirt from behind.

George Wickens plucks another Millwall cross out of the air.

The home side are lacking in ideas at the moment and Lincoln are dealing with what they have to offer.

Much better from Amario Cozier-Duberry as he picks up the ball deep on the right, drops a shoulder to bustle past his man, feints past another and unleashes a 25-yard curler with his left peg which is straight at Nathan Trott.

Watford have had the better of this half, undoubtedly.

The Hornets have just carved out the best move of the match so far.

Luca Kjerrumgaard finds Myron Boadu, who has peeled away from the last line of defence, but Billy Koumetio recovers and produces an excellent last-ditch challenge to deny the forward.

Watford recycle it but Kjerrumgaard fires over the bar. The beleaguered hosts have shown a bit of urgency and have moved the ball a fair bit better than Charlton thus far.

Cardiff are defending with good discipline too and force Boro all the way back to their own half after Kyle Joseph initially makes headway down the left.

It's worked back to Amario Cozier-Duberry on the right but his curling cross is too close to Nathan Trott.

Boro fans getting a touch frustrated. They are going to have to come from behind once again at home if they are to pick up the points today.

They'll certainly be more goals in this game. With the way Cardiff play and the way they we play we could see some more.

The game is chalk and cheese with the way we played against Stoke. At this moment in time it's not quite working for Boro.

Cynical from Joel Bagan who brings down the marauding Aidan Morris on halfway as Boro fly forward on the break like the red arrows after pinching possession in their own half.

One for the team, and potentially very worthwhile.

Millwall do now seem to have calmed things down a bit.

They were getting sucked into Lincoln's hasty approach to everything.

The Lions are yet to test George Wickens in the visitors' goal.

Another decent opening for Watford.

They go long and Marc Bola wins his aerial duel. The ball is picked up by team-mate Myron Boadu who wriggles free of Kayne Ramsay but drags his shot wide of goal.

Just over 20 minutes played and we have seen well over 200 combined passes in this game so far, but it's Cardiff who have had nearly two-thirds of possession.

Good spell from Boro this, and Brian Barry-Murphy has just gone into the referee's notebook for some kind of dissent to the fourth official as he feels things aren't going his side's way.

Callum Brittain is freed by a lovely pass from Aidan Morris on the right but his cut-back rolls all the way to Neto Borges on the edge of the box whose off-balance first-time shot flies high and wide.

Millwall goalkeeper Filip Marschall is fine to continue.

Incidentally, not only is the goal from Andrei Coubis his first for the club, but it is also his first in English football.

Cardiff clinging on.

Kyle Joseph wins the ball back and tees up Aidan Morris who sees a shot charged down by Gabriel Osho - he suggests with his hand - but the ball rebounds to Amario Cozier-Duberry who takes a nice touch and fires in a far-post half-volley which Nathan Trott does well to get down to his right to turn past the post.

Millwall have to use their heads and calm down a bit. It's all a bit messy with passes all over the place out there.

Alex Neil will need his side to get back to basics because it seems like they've forgotten. They've almost fallen into Lincoln's hurried play of chaos a little bit
