That was a special, special try that was made by Brad Singleton coming on the short side. He rode a few tackles and got the offload to Liam Sutcliffe, who showed great deception to level the scores. Singleton has genuinely been the best forward in this game.
It was a tough kick but Kallum Watkins has been nailing them consistently all season.
For about half a season, I did question who would take the goal kicks - they tried Rob Burrow and others, but Watkins has stepped up and looks like he's been doing it all his life.
Liam Sutcliffe
Brad Singleton sets this try up, driving towards the Hull line, but taking the defence by surprise as he pops a quick pass to his left rather than taking a tackler on.
From there, it's all about Liam Sutcliffe, as he turns Albert Kelly inside and out before sliding over the line.
Kallum Watkins' successful conversion puts Leeds back in the driving seat.

Kallum Watkins looks to inject some creativity into a Leeds attack, but his offload is pinched out of the air by Mark Minichiello, who has had an excellent game.
The Rhinos are starting to win the territory battle once again after a long period of Hull control.

Leeds look to get back on the front foot with a powerful run from Mitch Garbutt.
He tries a little too hard though, spilling the ball forward as he fought for extra metres.
The hosts are then pinned back by a low kick towards the in-goal area, but a high tackle from a Hull FC player relieves the pressure.

That wasn't a bomb to the winger - they call it landing it on the three man. When your attack isn't flowing, you put any kind of kick up and at the end of the day, that was a 50-50 that's landed at the right place in the right time for Hull. Game on.
It changes the complexion of the game now. It's been really edgy and position-based, but Hull will look to manage their sets now.
It will force Leeds to look for more offloads and to try and take more chances.
Sika Manu
Hull lead for the first time!
They work the ball quickly first to the left-hand flank and then back inside, before Marc Sneyd's kick is batted back to Sika Manu to slide over on the right.
Sneyd then adds the two points to make it a four-point lead.
Leeds Rhinos 12-10 Hull FC
There was no obstruction after all, but it's almost impossible to tell if the ball was grounded.
It's terrific last-ditch defending from Hull to stop Singleton getting it down clearly as he went to ground.
In the end, the video referee probably had no choice but to go with the on-field call.
Quote MessageJamie Shaul's hand was underneath the ball and I think that's what led the video referee to make his decision. And that defending now becomes a massive moment in this game. Hull FC defended their line very well during that period.

...but no try has been awarded on the field.
Brad Singleton's thundering run ends up with him charging over the line and grounding the ball down, but the referee thinks there's an obstruction.
It's gone upstairs for review.
Leeds Rhinos 12-10 Hull FC
Against the run of play, Leeds are handed a chance at a third try.
Mitch Garbutt intercepts a Hull offload on fifth tackle and races down the field towards the goal-line, but he doesn't have the legs to outrun Hull's defence.
The support isn't quick enough to get alongside him either and Hull cling on.

We've seen a totally different Hull FC side this half to the one we saw in the first.
They've got back to what they do well, carrying the ball strongly and getting down the field.

Jake Connor could have scored that himself, but managed to attract Ryan Hall and then deliver the one-handed offload.
That was a tough kick for Marc Sneyd but it was all class on the try. It's absolutely game-on now.
Mahe Fonua
Leeds' Ryan Hall pays the price for not defending that kick a few moments ago as Hull are given the scrum deep in Leeds territory.
Hull work the ball quickly out to the right, where the always dangerous Mahe Fonua is on hand for a simple finish.
Marc Sneyd misses a difficult conversion attempt from the touchline, but Leeds' advantage is down to two points.
Leeds Rhinos 12-6 Hull FC
Carl Ablett is punished for a high tackle on Hull's Gareth Ellis, the visitors maintaining the pressure they were applying at the end of the first half at the start of the second.
A high kick to the right hand side on fifth tackle goes out of play off someone, but it's tricky to tell who got the final touch.

Marc Sneyd kicks off the second half.
Can his Hull FC side end a 10-year wait for victory at Headingley and reach the Grand Final?

Remember, tonight's winners will meet Castleford in the Grand Final next week.
Tigers coach Daryl Powell gave his reaction to his side's win to BBC Radio Leeds:
"It was such a crazy game and really tight all of the way through. The 10-point cushion should have been enough but we were a bit soft on the tryline and never really got our game together.
"There were disappointing things, obviously, but II'm just delighted for everybody at the club that we've given ourselves a chance of winning the whole thing.
"Extra-time is always interesting - it makes a big difference now with the seven tackles and going for drop-goals.
"I thought we went for the first one too early and gave seven to them, then they did the same for us.
"That drop-goal was world-class - for Gale to get it over the top of the onrushing defenders was pretty special. He does some real good things with the ball and has been great for us all year - he's been a consistently good player for us."

There is, of course, one thing missing from this game.
I'm talking about the South Stand above, which has been demolished as part of a £35m redevelopment of Headingley.
Demolition of the stand started a while ago, but it has now been completely removed.
It's not like the action on the field hasn't been worth watching, but I can't keep my eyes off all the rubble.
One of the big stories in rugby league this week has been Salford Red Devils owner Marwan Koukash's decision to hand over control of the club to a community trust.
Koukash took over Salford in 2013 and saw then reach the Super 8s this season and the Challenge Cup semi-finals.
He has been speaking to BBC North West Tonight about his decision, which he hopes will help make the club "self-sufficient".

It's not been slick, it's not been pretty, but it's been exactly as I've expected it. Rhinos are well in advance and deserve this lead - I've been impressed with their defensive energy and their efforts to repel Hull.
Sometimes defending back-to-back sets can give you as much confidence as a good attack. Leeds have had to do that at times and that will have shown them that they can do that under pressure.
Hull, in my opinion, have work to do. They've been disjointed in attack and haven't shone at all.
Leeds dominated proceedings for a good 25 minutes of the first half, but Hull slowly worked their way back into it, with Gareth Ellis' try keeping the deficit down to six at the break.
It'll have to go some way to top last night's thrilling first semi-final, but this game is building up to be a pretty good one too.
