Aaron Lewis is withdrawn by Nigel Clough, with Hiram Boateng coming on for the final half-hour and change.

Keanu Baccus wins a free-kick from Christoph Klarer right on the edge of the Blues area...

It's a farewell to Bristol Rovers' Ruel Sotiriou, who has to be sacrificed to regain balance after Shaq Forde's sending off.

Jack Hunt joins the fray.

Another chance for Morecambe - this time Ben Tollitt's ball finds Marcus Dackers but the striker's effort is dealt with by Max Thompson.

The game is more stretched now and Kelly N'Mai has a shot blocked for Salford.

Colchester sense a swift counter attack but Jack Payne makes his run slightly too early and is caught offside.

It's 14-1 to Birmingham in terms of shots, but for all their dominance the margin remains just one goal - Willum Willumsson's neat finish on 10 minutes.

Alfie May is coming on to try to improve their stats, with Jay Stansfield making his way off as he returns to full fitness.

Some players come across as not that bright.That is extremely unintelligent from Shaqai Ford when he's already on a yellow card.

He realised he wasn't get the decision and kicked the ball away and now Bristol Rovers are now down to 10.

Morecambe are well in this game, belying their lowly status and Callum Jones fires a shot wide.

Ethan Laird nips past Stephen McLaughlin on the right and the Stags skipper lunges in, conceding a free-kick a yard outside the corner of the box and earning himself a booking, which he strongly disagrees with.

Two changes for Colchester as on come Arthur Read and Harry Anderson for J-K Gordon and Oscar Thorn.

Pointless but deserved.

Shaq Forde is off for Bristol Rovers with a second yellow card after some strong words to the referee with a side of kicking the ball away.

That free kick he was lobbying for is nothing but a blip on the radar compared to the work he's just given his fellow teammates.

Kylian Kouassi feeds off Ossama Ashley's ball in the Colchester box but the Salford man's shot is weak and Matt Macey makes a comfortable save.

Play switches to the other end and Tom Hopper pulls the ball back to Jack Payne whose shot is saved and then Oscar Thorn's follow-up is blocled.

Jay Stansfield tries to work some space near the byline on the left of the Stags area but big Jordan Bowery steps across to see the ball across the whitewash as Stansfield tumbles to ground.

A physical mismatch, that one. Blues fans want a penalty. Not in a million years.

Panic stations for Reading's Tyler Bindon and Joel Castro Pereira.

Bindon strongholds out the emerging bright green Rovers shirt in the box but things get a little confusing when he gets close to his keeper. The centre-back is forced into kicking the ball out of play to gift the visitors a set piece.

Birmingham are trying to finish this off...

Tomoki Iwata pinches possession in the Mansfield half and Blues pile forward before a cross into the box is cleared only to Paik Seung-Ho, who steps inside a man before thundering a 20-yard effort straight at Aden Flint who is an absolute man mountain.

Gas substitute Isaac Hutchinson puts in an effort but it soars well away from goal.

Though it's been a better start to this half for Bristol Rovers than the first.

Colchester look like they might step things up in this second-half.

Liam Shephard dithers on the edge of the area and is dispossessed but a rash cross flies over the bar.

Some lovely intricate build up play from Blues ends with Keshi Anderson swinging a right-footed cross in from the left which Lyndon Dykes meets with a stooping header which is straight at Christy Pym in the Stags goal.
