It is a good save by Blackman but one he should save. More importantly he palmed it away from goal to ensure Iheanacho didn't get a chance to score another FA Cup goal.

Wilfred Ndidi tries his luck from distance, it's well hit and swirling through the air but Sheffield United keeper Jamal Blackman dives to punch clear.

"A nightmare start for Hull. Willian is so good in these tight positions, and when he let go I think the keeper knew it was going to hit the back of the net.

"People on social media were asking why Willian was playing tonight - that’s why you play your best players. Now it could be an easy evening for them."

Sheffield United boss Chris Wilder kicks a bottle of water as he walks back from the edge of his technical area to the dugout to have a word with one of his coaches. After a bright start, the Blades are having to do a bit of defending now.

Jamie Vardy has been getting plenty of stick from the travelling fans due to his Sheffield Wednesday allegiance but he almost opens the scoring as he finds space down the left and tries to place an effort inside the far post but he's just wide.

And then Demarai Gray smashes an effort well over to bring a disappointing end to a decent Leicester attack.

Patient passing by Leicester as they try to build an opening. Just over 10 minutes in and they haven't troubled Jamal Blackman in the Sheffield United goal yet.

Sheffield United have nothing to lose. Leicester are the Premier League team, the onus is on them. Sheffield United have injuries, they can go out there, enjoy it and try to win the game.

James Wilson then finds a bit of space on the left but his cross towards the near post is caught by Kasper Schmeichel.

Iheanacho had the time and the space but I'm not sure what he was trying to do? Maybe he was shooting? That is frustrating for the likes of Vardy and Mahrez.

Lovely back heel by Kelechi Iheanacho for Riyad Mahrez. The winger's through ball for Jamie Vardy is blocked but Iheanacho keeps the ball alive, before fluffing his cross by sending it high and wide.

Nii: Any Chelsea lineup minus Bakayoko makes me happy. Never seen an awful footballer in Chelsea shirt all my time watching football.

Rashida: If these upcoming fixtures don't motivate these Chelsea players to get out of 1st gear God knows what will!! Can only hope Conte is the right man to help us progress

Almost time for kick off at Stamford Bridge, so here's a reminder of the team news.

Chelsea make six changes from the 3-0 win over West Brom, as cup regulars Willy Caballero, Ethan Ampadu, Danny Drinkwater and Willian come in - alongside captain Gary Cahill and debutant Emerson Palmieri.

Chelsea: Caballero, Rudiger, Cahill, Ampadu, Zappacosta, Drinkwater, Fabregas, Emerson, Willian, Giroud, Pedro.

Seven changes for Hull, who have about a dozen players ruled out. David Marshall starts in goal, with Michael Dawson, David Meyler, Evandro, Nouha Dicko, Adama Diomande and Kevin Stewart all starting.

Ola Aina and Michael Hector are among the seven to drop out, because they are on loan from Chelsea. Seb Larsson is suspended.

Hull: Marshall, Irvine, Dawson, Clark, MacDonald, Wilson, Meyler, Diomande, Evandro, Stewart, Dicko.

It's not completely a welcome return for Riyad Mahrez, with the winger getting a bit of a mixed reaction when his name was read out before kick off.

A couple of goals tonight and all will probably be forgiven.

Good start by Sheffield United as James Wilson's cross deflects off Wes Morgan's leg and the visitors have a corner.

Leicester have put out a very strong team knowing they need to get it right after the performance against Man City. It is going to be a tough night for Sheffield United.

When you have reached the highs of winning the Premier League, they want more. They don't want to be a team that just stays in the league. They want to be in finals and play in the Champions League.

Former Hull City midfielder Ryan Mason has been speaking to BBC Radio 5 live: "It’s been sad and emotional but at the same time I’ve had so many good luck messages and positive feedback from my career that it’s been nice at the same time. I’m looking forward to the next chapter now.

"The last 12-13 months were a constant battle, I was confident that I could get back on the pitch. But probably a week or two weeks ago I got some conclusive and strong news. I had a week or two to get over it emotionally and that’s why the timing was right to get it out there so I could talk about it and move on.

"Hull have been fantastic. The doctor has been with me throughout, I have probably been to 50 different surgeons, had blood test, scans, everything and he has been there every step of the way. The Chairman has backed me, everyone at the club wanted to see me play again but unfortunately that wasn’t to be. I can’t speak highly enough of them."
