Sunderland continue to dominate, Fulham continue to soak it up. Jermain Defoe hasn't had a chance of note of yet - but hang on, good strike from Seb Larsson saved by the shins of Marcus Bettinelli.
Taxi for Boyata! Dear oh dear, this is a terrible finish. James Milner's cross from a half-cleared corner falls invitingly for centre-back Dedryck Boyata, he leans back though and hits a man in the very back row of the bottom tier.
Seconds later Tomas Mejias makes a wonderful save in the Boro goal, getting down brilliantly to repel Milner's drive. Goal coming.
Leicester City are forced into a change as Liam Moore, who gave away the penalty, is limping and cannot continue. On comes Marcin Wasilewski - like-for-like.

"For the first time in the game West Brom found a bit of space in front of the Birmingham defence (see 15:25) and Victor Anichebe provides a really clinical finish, after a great first touch, to score in off the post."
I saw Kenwyne Jones walking through an airport once. He is absolutely massive. And he's far too big and strong for the Reading defence to deal with, towering over everyone to thump home a header from a Peter Whittingham corner.
Didier Drogba and Loic Remy have both gone close as Chelsea look to put their foot down and kill the tie off.

"Frustrating for Bradford. If you lose to Chelsea to a wonder goal then that's fair enough but that one was avoidable. They must practise set pieces so many times. If you want to beat Jose Mourinho's side then you cannot concede as easily as that."
Sergio Aguero is still getting his match-sharpness back but the familiar strength and jinking run is back, bundling past a defender before slamming a shot into the side-netting. Almost.
First blood to the away side. Victor Anichebe is played in and the striker takes a touch before sneaking a shot in at the near post. A disappointing goal for the hosts to concede, but game on.
No goals at St Andrews but a cracking derby nonetheless. Saido Berahino shoots into the sidenetting for West Brom, before David Cotterill sees a shot saved for the home side.

"This is what the FA Cup is all about, neither side would mind going out so they are thinking of having a right go as they probably won't want a replay."
Darren Bent on the scoresheet! The forgotten man of football finds a way through Chesterfield's resistance, reacting first to a knockdown from a corner to pounce and head into the net.
Another minute, another goal at Southampton, this time going Crystal Palace's way. Wilfried Zaha plays in Yaya Sanogo whose placed effort is deflected into the net.
Chelsea have found it tough going so far but they take the lead with a fine improvised finish from centre-back Gary Cahill. Oscar's corner is bent in to the near post and Cahill extends a boot to flick into the net. Not quite Zola v Norwich, but close...
The hosts break the Deepdale deadlock in fine style, Paul Gallagher firing in a free-kick past the right hand of Blades keeper Mark Howard from around 25 yards out.
You can see why Boro are flying in the Championship, they move the ball with purpose and confidence. They work a lovely move to free Patrick Bamford but the striker is just offside.
At the other end Stevan Jovetic hits a horrible shot over the top and tries to blame the pitch. Which is perfect.
...no problems from the spot for Andros Townsend, he strokes home confidently and Spurs are ahead.
Roberto Soldado is fouled inside the area and a chance from the spot now for Andros Townsend...
Just the one goal in today's four Championship fixtures so far and it's a bit of a surprise. Bottom club Blackpool have come out quickest at Vicarage Road to take the lead against Watford, winger Andrea Orlandi with the goal.
Chelsea move forwards in unison down the left wing and it ends with Loic Remy hitting a shot which is easily held by Ben Williams in the Bradford goal.
