There's still nothing confirmed as to the situation, as even Umaga failing a drug test is simply speculation (although a very highly likely speculation). Valid reason or not, point is WWE could not afford to lose Umaga. The ratings are slipping every month and they have only a handful of main eventers left, with most needing time off for injuries or possibly leaving their contracts in the summer.
Case in point, if WWE doesn't have MVP, John Morrison, The Miz and a few choice others main eventing regularly on PPV by the end of this year, they are fucked.
