It's been a tough evening for them [Yates and Lowe].
They haven't done enough to stay on the field.

Cardiff 0-0 Swansea
Aaron Ramsey shows all of his class and experience to get Cardiff into an attacking position while the hosts are briefly down to 10 men as Charlie Patino receives treatment to his head once again.
But Ramsey fails to find a team-mate in the box.
Cardiff 0-0 Swansea
Jamie Paterson and Josh Ginnelly come on for Jerry Yates and Jamal Lowe.
Cardiff 0-0 Swansea
Yakou Meite bursts past Kristian Pedersen before squaring into the Swansea box, but Harry Darling is there to turn the ball behind for a corner.
Aaron Ramsey takes it, but it comes to nothing.

Swansea as a group, as a unit, have got to get themselves up the pitch.
Swansea don't want Charlie Patino on the ball, they need him closer to the 18-yard box.
Cardiff 0-0 Swansea
Charlie Patino collects a pass from Jay Fulton in plenty of space.
Josh Tymon makes a good run up the left wing, but Patino can't pick him out.
Swansea have had precious little joy out wide so far, nor have they had much success on the counter.
Moments later, Josh Tymon clatters into Aaron Ramsey.
Cardiff 0-0 Swansea
Aaron Ramsey whips the free-kick into the Swansea box, but Harry Darling clears.
The rain is pouring down here in Cardiff.
The hoods of fans in front of us have all just gone up in unison.
Cardiff 0-0 Swansea
Swansea have a little patch of possession, but Jerry Yates loses the ball so cheaply again.
Jay Fulton is booked for a poor challenge on Manolis Siopis.

Looking at Swansea's shape, I think they've moved to a five at the back with Darling slotting in.
Cardiff 0-0 Swansea
Manolis Siopis plays a ball out wide to Yakou Meite on the right.
He cuts inside and drills at Carl Rushworth.
The Cardiff man gestures to the home fans to raise the noise levels.
They duly oblige.
Cardiff 0-0 Swansea
This is such a scrappy contest. Neither side can really keep possession for a prolonged period and put the opposition goalkeeper under pressure.
Manolis Siopis takes his underlayer off and briefly continues with his shirt half on.
A few cheeky whistles from the home fans.

Personally, I don't think Matt Grimes is enjoying this style of football.

A lot better start to the half!
Cardiff 0-0 Swansea
No changes at half-time as you'd probably expect.
Yakou Meite robs Matt Grimes of the ball and unleashes a fierce shot goalwards.
It swerves in the air, but Carl Rushworth does well to palm it behind.
Cardiff 0-0 Swansea
The players are back on the field for the second-half.
Cardiff get us back underway.
HT: Cardiff 0-0 Swansea
It seems unlikely that either manager will make any changes at the break given how tight the first-half was.
Rubin Colwill, Callum Robinson and Joe Ralls are among those who you would feel will get minutes at some stage for the hosts.
Liam Cullen and Ben Cabango both scored in this fixture in April but remain on the Swansea bench.

I thought the first 25 minutes was really enjoyable, it was really end-to-end but it just really lacked that quality and what I would say, I have seen a better shape about Cardiff than over the last three seasons.

Danny Gabbidon
Former Cardiff City and Wales defender on BBC Radio Wales
I just think it's been really scrappy by both sides during the half.
Both teams have lacked quality.
I thought Cardiff started the better side and then Swansea got a bit of a foothold in the game.
From a Cardiff point of view from the backline into the midfield it's been comfortable in possession but when it's gone from the midfield into the front, there's just been that lack of composure.

A decent save by Rushworth.
Probably the best bit of quality we've seen attacking-wise from Cardiff.
Big chance!
Aaron Ramsey plays a ball over the top towards Ike Ugbo who nods into the path of Yakou Meite.
He spins and shoots, but Carl Rushworth does well to get down low to his left and make the save.
And that's the break.
