Still up? Then consider my hat doffed. I, though, am in need of sleep so it is time to knock our coverage on the head. Cheerio!

If that was indeed Neymar, which it looks increasingly likely that it was, then it is almost like the World Cup all over again, although this time it was completely his own doing after letting his frustrations gets the better of him.

The red card means he miss Brazil's next three games, a huge blow to their Copa America hopes.

A couple of red cards were flashed by the referee after the final whistle after that on-pitch fracas involving several players. Neymar looks to be the recipient of one as he went off down the tunnel, with Colombia's Carlos Bacca also seeing red.

The win also gets Colombia up and running in Group C, which is wide open with three sides on three points. It's also Dunga's first defeat in his second spell as Brazil boss.

That's it! Full-time and Colombia boss Jose Pekerman punches the air in delight at masterminding's his side's first win against Brazil in 24 years.

Lots of pushing and shoving between the two sets of players at the final whistle, though. Tempers bubbling over.

It is getting a bit niggly as the clock ticks down. Colombia happy to eat up time, Brazil desperate to get the chance for one last attack.

Four minutes of stoppage time is announced and four minutes for Colombia to hold on for a famous win against Brazil. They've not beaten them since 1991, when Brazil legend Ronaldo was nothing more than a promising youngster. His playing career has been and gone in that time, is Colombia's long wait about to end?

It is almost game, set and match to Colombia as James Rodriguez scurries along the edge of the area before shooting low and hard towards the far post. Just wide.

Oh it has just not been Neymar's night.

He peels away from his marker to chase a dangerous-looking ball into the box, but his first touch lets him down and the ball drifts out of play. Better control and that could have been the equaliser and Neymar knows it, slapping his thigh in frustration.

Filipe Luis has been pushed into midfield as Brazil swell their numbers to support attacks. They are pressing, but struggling to find that final ball as Philippe Coutinho sends a cross-shot wide of goal.

A change in midfield for Colombia for the final 10 minutes as Mejia replaces a tiring Edwin Valencia.

Changes for both sides as we enter the closing stages, midfielder Diego Tardelli on for Elias for Brazil, while striker Carlos Bacca replaces Teo Gutierrez for Colombia.

Victor Ibarbo replaced Radamel Falcao as the focal point of Colombia's attacks, but it is clear the big man has been told to get back in defence when Brazil attack, which they are doing at the moment. Can Colombia keep them out in these final 15 minutes?

This half has not matched the quality of football on show in the first half, with both sides going increasingly direct and looking most dangerous from set pieces. Colombia have half a chance when a free-kick from halfway is nodded on by Juan Cuadrado for Teo Gutierrez, whose shot is deflected behind for a corner.

Radamel Falcao pays the price for a poor display as he is replaced by Victor Ibarbo for Colombia with just over 20 minutes left. Brazil also make a change as Douglas Costa replaces Willian.

Jeison Murillo is down on the floor injured, a bit of claret coming from his nose. It looks like he took a bit of a knock when challenging Neymar for a long ball into the box. Looks like he is good to continue.

Jose Pekerman looks to be about to employ my go-to tactic on a certain football computer game, send on the pacey Victor Ibarbo when the momentum is with the other team. Not sure he will stick the striker on the wing like I do, though...

Speaking of shockers, Radamel Falcao is having one at the moment. Anonymous so far, with his first contribution of the second half being to give away a free-kick.

Oh my! What a miss! Jeison Murillo almost sees his good work from scoring earlier undone with a shocker of a backpass, leaving David Ospina way short. Neymar nips in, but his shot is charged down only for the ball to break to Roberto Firmino. He has an open goal in front of him but somehow smashes over. Shocking.

It has been much better from Brazil so far in this half, but they are almost caught out when their defence backs off Juan Cuadrado who, after a couple of step overs, lets fly with a rasping effort that flies just wide. Jefferson was beaten in the Brazil goal.
