Still Charlton push.

Harvey Knibbs turns the ball over in midfield before feeding Miles Leaburn but his shot is saved by Michael Cooper.

The Addicks players call for a penalty for handball against a Blades player in the box but nothing doing.

The supporters have been asked to stay in their seats but the rain doesn't seem to be abating.

If anything it's getting heavier.

The game was stopped on 80 minutes, what will they do?

Apparently the Ipswich manager didn't want the game to carry on...it's funny that his side were behind at Blackburn.

I remember playing for Ipswich back in 2010 when Roy Keane was manager and it was snowing. We were 2-0 up against Leicester but you could barely move on the pitch because it was so deep.

Of course Keane absolutely insisted the game carry on. He had everyone out sweeping the pitch.

Preston goal scorer and potential match winner Alfie Devine is done for the day.

Michael Smith comes on to see the game out.

Ooof Norwich come close.

They're trying to get a goal back to save their blushes before the final whistle, but the chances are few and far between.

Substitue Oscar Schwartau whips in a left footed cross into Jovon Makama who climbs the ladder and heads just over the bar.

Time has all but run out for the Canaries.

Charlton captain Greg Docherty heads just over from James Bree's cross.

Sheffield United are creeping towards their first point of the season.

Nathan Jones is sending on the cavalry for the visitors as Tanto Oloafe and Harvey Knibbs are introduced late in this game.

Knibbs came off the bench to score a late, late winner for the Addicks in their first game back in the Championship.

Can the former Reading player do it again?

It's pouring it down in Lancashire this afternoon and the referee decides to take the players off after 80 minutes.

The pitch is waterlogged - will they get back on?

Sheffield Wednesday aren't done at Fratton Park.

Yan Valery has a shot from the edge of the area but Ben Killip makes the save.

We're into the last 10 minutes of the 90.

Pompey skipper Colby Bishop gets his head on a corner but Owls keeper Ethan Horvath is equal to it to preserve his clean sheet.

It hasn't been Pompey's day.

The game has opened up completely now.

Patrick Agyemang has made a huge difference. He's spun the defenders twice and is lively. But this pressure also means our defence is more vulnerable.

More changes for the hosts as Tyrese Campbell and Callum O'Hare make way for Tom Cannon and Tahith Chong.

Still only really that Lloyd Jones header for the Addicks in the first half that has come close to a goal in a match which is looking increasingly like it's heading for a stalemate.

On the plus side, it'll be Sheffield United's first point of the season.

Derby are pressing now.

Patrick Agyemang has been an excellent substitution and first rolls a Preston man but is subsequently denied by the keeper, then has another go a little while later but gets blocked out.

Could the USA striker be the man to bring the Rams back into this?

Chris Wilder makes his first substitutions since returning to the Blades.

Off come Ben Godfrey and Chiedozie Ogbene with Femi Seriki and Louie Barry introduced.

Twenty minutes left for someone to find a winner.

Yuki Ohashi's role in the red card will be his most significant contribution as he's withdrawn for Rovers.

Andri Gudjohnsen replaces him while Ipswich make a triple change.

Sam Szmodics, Ivan Azon and Jack Clarke are introduced for Kasey McAteer, George Hirst and Jaden Philogene.

Sheffield Wednesday goal scorer George Brown comes off as Jamal Lowe is introduced.

Will the Owls see this one out?

John Mousinho sends on Makenzie Kirk for his debut in place of Adrian Segicic as the hosts trail.

The 21-year-old moved to Fratton Park from St Johnstone in the summer, what a dream debut it would be if he could find them a route back into this game.
