James Rodriguez is now in the book for a lunge on Hulk. Just over 20 minutes to go and it feels tense in Fortaleza. Someone needs to get hold of this game...
Chaos. An absolute omnishambles in the Brazil goalmouth as Colombia whip in a free-kick, David Luiz misses the header, it hits him on the back and there are three Colombians waiting for it! Mario Yepes eventually lashes in but the goal is ruled out for an initial offside.
That looks tight...
Not many smiles on the faces of Colombia supporters at a live screening of the quarter-final in Bolivar square in Bogota. Still it only takes a minute.....
And there is a yellow card! And it's significant too. Thiago Silva is booked for charging down goalkeeper David Ospina as he tried to clear his lines. He's booked - and he will now miss the semi-final if Brazil get there...
BBC Sport Chief Football Writer Phil McNulty in Fortaleza
"This World Cup quarter-final is very disjointed now and you suspect that suits Brazil nicely. It is Colombia who need to find some rhythm and cohesion to build a threat and the game is simply not allowing that at the moment. Brazil fans do not mind how their team get the job done - a hoofed clearance into the stand by Thiago Silva brought rapturous applause."
I'm not one for calling for yellow cards, but this is quite remarkable from referee Carlos Carballo. He hasn't booked anyone yet and Juan Cuadrado is the latest to get away with one, nailing Neymar in full stride.
Former England defender Martin Keown
"You'd think it was the last five minutes the way Brazil are finding touch. I don't see too many leaders out there. They've stopped playing. This is about the pressure, the tension and the emotion of the game."
Still half an hour to go. And there's only one side on top now - Colombia...
Nick, via text: "This game is made for a Kevin Philips-like Jackson Martinez nicking a late equaliser. Heard it here first."
Salford Dave, via text: "There's more whistles blowing in this match than a scooter song. Ref needs to chill."
There are plenty of teams in the tournament who are lacking a good number nine, and both of these can go on the list. Colombia do manage to put a slick move together, despite a bad pass from their nine Teo Gutierrez.
James Rodriguez takes a lovely touch on the chest again but when he lays it on one more Fredy Guarin hooks a shot over.
David Luiz and then Thiago Silva just hammer the ball away into touch. Away! Where's the composure?
Former England defender Martin Keown
"We haven't seen much of Cuadrado in this second half. If he can turn and run at Marcelo, he's in trouble. But the nerves are building a little on Brazil. They will want to keep possession and dominate the ball. But Colombia have got that fighting spirit and will keep going."
Former England defender Danny Mills

"When you're 1-0 up there is always a fear, especially when you have missed chances to score a second. We've seen James Rodriguez score some phenomenal goals in this tournament and Brazil will have to be wary."
Foul, foul, foul, foul. Very stop-start since half-time, that will suit Brazil just fine. They are 35 minutes away from a place in the last four.
The tempo, the verve, the intensity has gone from the game. Can Brazil manage this one and see out the win? That's the question now.
Jeremy Yeomans:, external "James getting kicked out of the game. Brazil should be as ashamed as trying to kick Cryuff out of '74, disgrace."
Matthew Bennett:, external "Fernandinho has to be booked. We want a flowing game but clever fouls and "taking one for the team" stunts the beautiful game."
Tom Dunn:, external "Slowly going off Rodriguez in this game. Awesome skill but diving like a salmon."
Do not adjust your sets...
Colombia bossing the early moments of the second half but with no real joy so far.

BBC commentator in Rio
"All eyes on Copacabana beach glued to big screens showing the match live."
James Rodriguez is fouled again by Maicon. Every time he gets on the ball he's being hit. Brazil know they have to stop him and they have so far.

South American football expert Tim Vickery: "I'd like to see Colombia bring on Juan Quintero, who is a lovely passer of the ball. I'm not sure about the fitness of striker Carlos Bacca, who was excellent in the warm-up games.
"While it is 1-0 there is a still a chance for Colombia. But I have seen Brazil in the past control a game through tactical fouling. The referee has seemingly given them carte blanche to do that."
Former England defender Martin Keown
"It's interesting to see how Colombia can accommodate to this new system. Pablo Armero, you can leave the left flank to him basically. James Rodriguez has gone out to the left but he'll look to play centrally when he can."
