'Croatia’s Ivo Karlovic has been forced to withdraw from the Olympic Tennis Event, having been unable to recover from a foot injury sustained since July.
That means that Germany’s Philipp Petzschner, already competing in the doubles with Christopher Kas, takes Karlovic’s place in the men’s singles draw and will face Slovak Lukas Lacko in the opening round.'
On winning DC and its overall importance in the discussion for all-time greats

The fact is, success in DC is largely determined by what country you come from or play for in the first place, which most players haven't had any control over.
In all honesty, it's karlovic's fault. If he withdrew around the same time nadal and monfils, I think haas would've made the trip to London.
Edit: was haas even on the alternate list?
no because the German committee didn't ask him to enter
His only chance to come would have been that the German committee asked him top come : he would probably have received an invitation from the ITF (not sure because the ITF gives priority to players who have been highly concerned with the Davis cup)
