This would be such a big win for Luton with Leeds and Stoke coming up.

They did it at Cardiff City but can they see it out here?

Zavier Massiah-Edwards is coming on for Watford, replacing Vakoun Bayo.

For Plymouth, Michael Baidoo and Callum Wright replace Matty Sorinola and Michael Obafemi.

Defeat today would mean Hull have taken just 19 points from 20 home games this season.

Hard to consider that anything other than relegation form.

Big final 10 minutes for them and of course for Luton in this one.

The Tigers bring on experienced winger Nordin Amrabat for Gus Puerta.

Abu Kamara's able to get a shot away for the home side but it's an easy stop for Thomas Kaminski in the Hatters goal.

Into the final 15 minutes now and the Luton goalkeeper really hasn't had to make decent save yet.

Another great Watford chance!

Rocco Vata wins the ball and feeds Vakoun Bayo with another perfectly-weighted pass.

Bayo rounds Conor Hazard but can only find the side netting.

Plymouth changes. Mustapha Bundu is hobbling off to be replaced by Bali Mumba, while Jordan Houghton is on for Darko Gyabi.

Luton now within 20 minutes of just their third away win of the season.

Three points here will move them to within one point of safety before the action later this afternoon.

As for Hull, they'll remain three points above the bottom three but, of course, that could change by the end of the day.

How did that stay out?!

Watford's corner is played back across goal by Rocco Vata and the ball just evades Vakoun Bayo. Can Plymouth survive this storm?

We're looking for the subs to make an impact but we're just giving it away.

Luton have have not really changed gear, they don't look under any pressure and are just strutting around. They don't look like a side who are second from bottom.

They've been better than us in this half.

Now the away side go to their bench as they look to get this one over the line.

Lamine Fanne and Millenic Alli are on for Liam Walsh and Elijah Adebayo.

Huge final 20 minutes or so coming up for Luton and Matt Bloomfield.

Watford, and Kwadwo Baah, just keep coming. Now he forces Conor Hazard into a fine save at his near post.

Suddenly Watford have width and they are gunning for Plymouth. This is a different game all of a sudden.

Wow, Watford forward Kwadwo Baah is straight into the action, flashing the ball across and eventually finding Giorgi Chakvetadze, whose shot is deflected onto the bar.

The home side make a double change as they look for a route back into this game.

Matt Crooks and Lincoln come in for Kyle Joseph and Kasey Palmer.

Lincoln is straight into the action as he gets on to a Lewi Coyle cross but can't direct an effort on target.

Balls into the air are not going to beat Christ Makosso, Mark McGuinness and Amari'i Bell. That's kind of been the theme for Hull City.

The home crowd are getting a little bit nervous because they know that if this stays the same then they are right back in the mix.

Another Watford change incoming. Kwadwo Baah, who has been out since January, is coming on for Tom Dele-Bashiru.

Giorgi Chakvetadze hurtles down the left and crosses but Vakoun Bayo can't connect in the area for the hosts.

At the other end, Ryan Hardie opens up a chance for himself but neglects to shoot and the move breaks down.

Hull City look to get back on level terms but Gus Puerta's header is straight at Thomas Kaminski in the Luton goal.

That's the Tigers' first shot on target by my reckoning.

That goal has taken the fizz out of the game.

The atmosphere has gone flat.
