Phil Dawkes and Shamoon Hafez

  1. Kidderminster 1-1 West Ham

    Kurt Zouma is down after falling awkwardly. He's only just back from injury so this is a concern.

  2. 'Sigh of relief'

    Kidderminster 1-1 West Ham

    Rob Green
    Former West Ham goalkeeper on BBC Radio 5 Live

    Another sigh of relief from the Kidderminster fans. Andriy Yarmolenko just drifted offside but it's more pressure from West Ham.

  3. SUBSTITUTION

    Kidderminster 1-1 West Ham

    Keith Lowe is on for Kiddy. He is a 36-year-old centre-back. A club legend. Can he help his side see this out for one last shot at glory?

  4. Chelsea 2-1 Plymouth

    Chelsea are not comfortable at the back, that's for sure. Plymouth aren't going away without a fight.

  5. Chelsea 2-1 Plymouth

    Eight minutes for Plymouth to try and find an equaliser.

  6. Kidderminster 1-1 West Ham

    The ball is in the net for West Ham!

    The flag is up, though! Repeat, the flag is up.

    It is Andriy Yarmolenko who is offside in the middle as the cross comes in and the ball is slotted in.

  7. Kidderminster 1-1 West Ham

    Dion Dublin
    Former Aston Villa striker

    Brilliant from White! "Could you clip that one up for me, lads?"

  8. SUBSTITUTION

    Chelsea 2-1 Plymouth

    Goalscorer Cesar Azplicueta gets a generous round of applause as he makes way for Trevoh Chalobah.

    Lukaku and Werner should look at the Chelsea's defenders for inspiration. Not good enough.

    Arthur Romsey

  10. 'Fans need to lift players'

    Kidderminster 1-1 West Ham

    Rob Green
    Former West Ham goalkeeper on BBC Radio 5 Live

    It's just gone a little bit flat again and Kidderminster's fans need to lift the players. They are a few minutes away from penalties and possibly something very special.

  11. CLOSE!

    Chelsea 2-1 Plymouth

    It's agony for Plymouth, Ryan Broom's thumping shot from the edge of the area is blocked. He caught it really well.

    Ryan Hardie's follow-up is also stopped by a blue shirt.

  12. Kidderminster 1-1 West Ham

    Jaiden White with the tricks. He pulls a cheeky back-heel turn to get away from Declan Rice. One to tell the grandkids about.

  13. Chelsea 2-1 Plymouth

    Dan Scarr loses the flight of the next corner and cannot convert.

    Kidderminster 1-1 West Ham

    Fifteen more minutes.

  19. SUBSTITUTION

    Kidderminster 1-1 West Ham

  20. Kidderminster 1-1 West Ham

    Here is why we're in extra-time at Aggborough. Declan Rice, right at the death for West Ham...
