A first-minute goal by Dempsey and a late winner from substitute John Brooks helped USA avenge their 2010 exit to Ghana with a 2-1 victory over the Black Stars in Natal.
Dempsey said: "The result shows our character. We got the goal the goal early in the game and that caused us to be a little bit more defensive. I thought Ghana played really well, but I thought that we didn't help ourselves at times in terms of keeping possession. When they got the equaliser, I thought that we might get a point out of the game, but credit to our team, we kept fighting and we got the goal. We didn't play our best, but we ground out the result.
"I think my nose is broken. I didn't consider coming off, I just wanted to go on for as long as I could, but I had trouble breathing. I was coughing up blood a little bit from the back of my throat, but I felt fine and that I could keep going. I did feel a little bit tired towards the end, but hopefully I'll be able to start breathing through my nose again before the next game."
