I doubt it. Was the bark on? I have left untreated, unsealed elm logs lying on the woodpile for more than 3 months WITH the bark on and they are fine for bows. I left an ash trunk with the bark on on ze ground for almost 6 months, its good strong wood still.
If it doesn't show any rot, its probably OK.
Were the ends sealed? Split off a small piece once you split it into staves and then see how it bends.
