Full Time - Colchester United 3 Brentford 2
92 mins - The Bees are throwing everything at Colchester but are almost caught on the break but Nwachuku chooses to shoot when he has Bonne is space. The shot is easy for Bransgrove.
90 mins - Nwachuku beats the offside trap again and bears down one-on-one with Bransgrove but the young keeper stays big and makes a fine block.
85 mins - The Bees make their final sub bringing on Fabian Rowe for Max Herbert.
84 mins - Colchester United 3 Jack Simmons Brentford 2
The impressive Simmons grabs his deserved goal but its another poor goal to concede from Brentford's point of view. A hopeful ball slips under Milenge's foot and finds Simmons. He backs Milenge into the box before firing a shot in which Bransgrove gets a hand to but can't keep out of the bottom corner.
74 mins - Colchester United 2 Macauley Bonne Brentford 2
Colchester take a quick free-kick which releases Simmons. His initial cross is cleared but Curtis slips in Bonne with the loose ball. The Colchester striker beat The Bees offside trap and had ages to pick his spot and roll the ball home
71 mins - The Bees make their second substitution with Gradi Milenge replacing Walter Figueira
69 mins - Good work from Senior wins a corner for The Bees. It bounces across the edge of the six yard box finding its way to Figueira at the back post. He hammers it back into the middle where there are half hearted shouts for handball from Brentford.
67 mins - Another defence splitting pass from Curtis releases Nwachuku. He drives into the box but Stone gets a good block in. Curtis gets onto the rebound but his acrobatic efforrt is straight at the keeper.
62 mins - Colchester United 1 Brentford 2 - Courtney Senior
It proves to be a great substitution for Brentford as Senior scores with his first touch. Rosique takes far too long to clear and Senior nips in and steals the ball. He is then left with the simple task of rolling the ball into an empty net
61 mins - Louis Lancaster makes a change replacing the goalscorer Stockwell with Courtney Senior
58 mins - Pilbeam tries his luck from 20 yards but his firmly struck low effort is a regulation save for Rosique
56 mins - A lovely clipped pass from Jack Curtis eludes Lionel Stone. Nwachuku races on to it and fires across the six yard box but Bryan is there to knock it behind for a corner which is easily dealt with.
54 mins - Brentford in a dangerous position but Onovwigun chooses to shoot with Figueira un-marked to his left. Onovwigun's shot rolls well wide
52 mins - It has been a very cagey start to the second half with both teams being wasteful in possession in the final third.
Colchester get us back underway here
Half Time -The referee brings an end to a half that has been high on energy and endeavour but low on clear cut chances. Josh Stockwell's fine effort gave the Bees the lead against the run of play but the Colchester equaliser, scored by Macauley Bonne, owed much to the very impressive Jack Simmons on the left wing.
41 mins - Colchester should be going into the break in front. Thomas Lapslie has time in the midfield to slip in Jack Curtis. Curtis isn't offside but he screws his shot well side from 12 yards with only Bromsgrove to beat.
37 mins - Callum Rogers seizes on a poor touch by Onovwigun and curls a 25 yard effort towards goal with his left foot. It dips just too late and goes over the bar but it had Bromsgrove beaten in the Bees goal.
34 mins - O'Donoghue roams forward from left-back and tries his luck from 30 yards. Tomasevic gets a flick to it and deflects it narrowly over for a corner.
31 mins - Simmons is involved once more. This time his clever reverse ball slips in Nwachuku but his effort from a tight angle is straight at Bransgrove who palms it away before Onovwigun completes the clearance.
28 mins Colchester United 1 Macauley Bonne Brentford 1
Simmons has been Colchester's best player so far and he has a large hand in the equaliser. His cross from the left is nodded home by Bonne from on the six yard box.
24 mins - Colchester's best chance of the half. Nwachuku is released through the middle but his tame effort is straight at Bransgrove. Bonne has the rebound but his effort is knocked behind for a corner by Tomasevic.
15 mins Colchester United 0 Brentford 1 Josh Stockwell
The Bees take the lead against the run of play. Good work by Onovwigun in the middle riding a couple of tackles before he gives the ball to Stockwell just inside the Colchester half. The Bees' striker is allowed to wander forward before picking his spot beautifully from 25 yards and curling it into the bottom corner.
12 mins- More good work by Simmons and this time it is Bonne with the effort but it is deflected and all the sting taken out of it. An easy gather for Bromsgrove
9 mins - Colchester have the ball in the net but it is ruled out for offside. Jack Simmons with good work down the left and Nwachuku with the finish but the tall striker was ruled to have moved too early.
5 mins - Macauley Bonne beats Max Herbert to the ball and drives into the box. His cut back finds Nnamdi Nwachuku and his deflected effort is well tipped round the post by James Bransgrove. From the resulting corner George Pilbeam is on hand to clear Bonne's header off the line.
3 mins - Lionel Stone gives away a free-kick in a very dangerous position on the edge of thebox but the effort from O'Donoghue is tamely into the wall
