41 MINS - Yedlin has pace to burn. Again finds himself in behind the Belgian defence and crosses it back for Jones, who mishits it. Big chance there for the USA. The right flank is basically empty. No tracking back from the Belgians.
Just two minutes from half time and it's still 0-0. Klinsmann has gotta be happy with this first half. Decent chances for USA and solid at the back. Belgium still not firing on all cylinders.
Another nice save by Howard -- no rebound -- just into first half stoppage time. 3 minutes on the clock
45+1: Origi breaks down the right flank, crosses it to De Bruyne who smashes the shot from outside the area into Tim Howard.
Halftime. U.S. and Belgium are scoreless in Brazil
Second half, here we go..
Twelve of the 15 goals in the knockout stages so far have come after half-time ...
Second half underway in Brazil
CHANCE BELGIUM: De Bruyne crosses it to Mertens, who flicks it off the back of his head and it loops down to ward Howard, who palms it over his crossbar for a corner
53 Mins: Still 0-0 but USA defending deep in their own half. You feel the pace of the game is going to take its toll on the USA midfielders who are having to track back hard. Hazard still looking quiet. But for how long?
CHANCE BELGIUM! And how did they miss. Vertonghen crosses it from the left across the six yard box and both De Bruyne and Origi miss it. Just need a tap in. Lucky escape.
Belgium header off the top of the crossbar and over. U.S. escapes again
56 MINS - Origi hits the bar with a header from long range. Howard just leaves it. Knew it was going over? Or misjudgement?
And Howard with another big save, cleared out by the defense
Much like the first half, Belgium controlling pace -- and the ball -- for the first 10+ minutes of the second 45
VERTONGHEN IS ON FIRE: The ball comes in from range and Vertonghen just unleashes a left foot volley which goes just past Howard's post. Smashed it.
Belgium makes its first sub, Mirallas for Mertens in the 61st minute
60 Mins - Origi goes down the left and gets in behind the defence. Crosses it to the near post and Mertens tries a flick but it goes out for a goal kick. USA working hard but Belgium look like they've got that extra bit of class at the moment.
Yedlin showing his potential going forward, terrorising the Belgian defence, but leaves a massive gap at right back. Belgium look to counter again but the ball is cleared. It's so end-to-end, I can barely type fast enough.
Another shot just wide of the frame by Belgium. 70th minute now, and somehow still scoreless
CHANCE BELGIUM: Witsel picks it up on the edge of the area and puts his foot through it. The shot is low but goes wide of Tim Howard's goal, but only just. USA starting to look tired, Klinsmann needs to freshen things up.
Looks like Wondolowski will be coming on
It'll be Chris Wondolowski for the U.S. to replace Graham Zusi in the 72nd minute
Howard turns away a sure goal. Corner to Belgium
WHAT A SAVE FROM HOWARD: Mirallas is in on goal, strikes it with his left foot and guess what, Tim Howard saves it. The guy is unreal. All came from Yedlin losing the ball to Hazard. That counter attacking game costing the USA there.
Omar Gonzalez turns an ankle landing after a jump on the corner. He'll stay in
Howard with another diving save! He's been the difference in this game
It's another save from Tim Howard and you've gotta feel without him would they even be in this match? He was epic in the Group stages and now he is keeping the USA in this. Have I mentioned it's end-to-end already? I feel tired watching it.
