It depends on how long it was in the urine, I think. If you noticed it quickly and immediately washed it, it shouldn't absorb the smell. If it was there for a while or it has been sitting unwashed, it could have a very small amount of urine smell. Not enough for you to notice, most likely, but if you think it will make Jojo more likely to pee in the crate, toss it.
