Lee Tomlin is operating from the left flank after the Cardiff substitutions, with Neil Harris hoping the switch from a central attacking midfield role will see him get some more joy.

Fulham have done a pretty good job on Tomlin so far.

Josh Onomah does well again for his side, holding possession and eventually winning a throw.

He is having a fine game.

Fulham have dominated possession in the second period, but Cardiff's substitutes have at least given the hosts some fresh energy.

Will Vaulks is a long throw specialist, but he tricks Fulham by throwing short to Lee Tomlin and his low cross is scrambled clear.

Neil Harris makes three changes, with Will Vaulks, Josh Murphy and Danny Ward coming on.

Can they make an impact?

Fulham are on top - and Neil Harris is set to respond by making his first changes of the evening.

Fulham work the ball well on the edge of the Cardiff area, with Harrison Reed and Tom Cairney involved, as Cardiff are forced to scramble clear.

Marlon Pack tries to switch the play to Leandro Bacuna, but his pass is too strong and goes behind for a goal-kick.

Cardiff are toiling a little right now.

Fulham are in total control.

At this point, you would assume Neil Harris is thinking about making changes.

After all, Cardiff have scored more goals from substitutes than any other team in the Championship this season.

Who could that be tonight? Danny Ward? Josh Murphy?

Whoever it may be, Cardiff need a spark from somewhere because they are being outplayed.

Fulham play a long ball which Josh Onomah knocks down for Bobby Decordova-Reid just outside the box.

He connects sweetly with his shot - but the ball is always rising and sails too high.

Fulham are playing keep-ball, with Cardiff sitting deep for a spell.

Neil Harris' team need to find a response.

Fulham do ever so well, and that is a brilliant piece of individual skill from Onomah.

He has no right to waltz through there, and he has the composure to slot it past Smithies.

Harrison Reed has the chance to send a free-kick into the Cardiff box, but once again a Fulham set-piece is wasted as he overhits it and Alex Smithies gathers.

There has been very little between these teams so far in this game, but Josh Onomah had been impressive for Fulham even before that high-class goal.

He has delivered on the big occasion.

Fulham bravely play the ball across their own penalty box and escape with possession - but that is the way they do things.

Neither team has threatened as yet in the second period.

We are off and running in the second half.

Can one of these sides seize the initiative in this play-off semi-final?

Fulham manager Scott Parker probably did not like what he saw in the opening quarter of this contest, but his team improved as the first half wore on.

The visitors were the side threatening as the break approached having had to focus on keeping Cardiff at bay in the early stages.

With the second half and the second leg to come, this play-off semi-final remains too close to call.

Cardiff got away with one, Cairney has scored a lot of goals from positions like that.

Hoilett gets caught on the ball, its squared to Cairney but you expect the net to ripple there.
