Harrison Reed's race is run.

Harry Arter replaces him in the Fulham midfield.

Reed has impressed for the hosts today.

Henrik Dalsgaard gets in behind the Fulham defence after Ivan Cavaleiro fails to track his run, but Harrison Reed clears the right back's cross.

Then Josh Dasilva gets onto the ball after finding space on the right.

He advances into the box, but bends his wide of the home goal.

No hat-trick sadly for Swansea striker Rhian Brewster as he makes way for Wayne Routledge.

The visitors also throw on George Byers for Jay Fulton in midfield as Patrick Roberts is the latest Boro player to pick up a yellow card.

Middlesbrough still to register a shot on target with just over 10 minutes to play.

Brentford are threatening now, as Said Benrahma flashes a ball across the box.

Shandon Baptiste can't pick out a team mate after picking up the pieces.

The sub then gets into the box but his low cross is straight at Marek Rodak.

Heading into the final 15 minutes, you feel one goal will win it from now on...

Derby get us back under way at The Den for the second half.

Jonathan Woodgate "empties his bench" to borrow a rugby union phrase as he makes his last two permitted changes for Boro.

Ashley Fletcher and Britt Assombalonga are on in place of Rudy Gestede and Lukas Nmecha.

Into the last 20 minutes.

Brentford forward Ollie Watkins has a shot in anger from the edge of the box, but blazes well off target.

He hasn't had too many sights on goal so far today.

Fulham make a change as Ivan Cavaleiro comes on for fellow winger Neeskens Kebano.

Brentford make the first substitutions of the game, as Emiliano Marcondes and Shandon Baptiste come on for Mathias Jensen and Tariqe Fosu.

Time for second-half drinks at The Riverside.

It's still as it was at the break on the scoreboard though. Swansea looking very content and comfortable as none of Boro's three changes since half-time have had an impact yet.

Brentford get a free-kick some 30 yards out after Harrison Reed chops down Ollie Watkins.

The Bees work a routine and win a corner, but we'll have another drinks break before they take it.

Incredible reaction stop from David Raya!

The Brentford keeper pulls a save out from the top drawer to deny Aleksandar Mitrovic.

The Fulham marksman flicked a header goalwards from the edge of the six yard box after being picked out by left-back Joe Bryan.

The game is beginning to open up.

Both sides can't quite make the most of attacking opportunities, as a rare wayward pass from Tom Cairney slows down a Fulham counter-attack, and then Brentford playmaker Said Benrahma can't wriggle past two defenders despite his best efforts.

Third Boro change as they continue to chase this game.

Marvin Johnson adds a different element in attack as Hayden Coulson makes way.

At the hour mark and still plenty for the hosts to do to get back into it.

All square at The Den, with Matt Smith’s header giving the home side the lead but that was cancelled out by Louie Sibley’s strike.

A good half of football.

From the corner, David Raya has to be alert to save a goalbound header from Fulham striker Aleksandar Mitrovic.

Good reactions from the keeper, but a save you'd expect him to make.

Brentford left-back Rico Henry gets in a good position and looks like he will whip in a cross from the byline, but runs out of pitch just at the crucial moment.

Straight down the other end, and Fulham right-back has a long-range effort deflected behind for a corner.

Nothing in terms of noteworthy chances for either side since the resumption.

Swansea make a first change as Jordan Garrick comes on for Aldo Kalulu.

Aleksandar Mitrovic gets clear of the Brentford defence and thinks he's opened the scoring after stroking the ball past David Raya.

But the offside flag is up, despite the Serbia striker protesting.

Replays show Mitrovic was miles ahead of the centre-backs from Anthony Knockaert's through ball.

Mahlon Romeo goes close for the Lions as he cuts inside onto his left but his drilled effort hits the the side netting of Ben Hamer’s goal.

Brentford start to find their rhythm, and Tariqe Fosu whips in a cross which is cut out by Tim Ream, who volleys clear.
