I know most of us have done it and got away with it, but a potential risk of sitting in water for a while is the (theoretical at least) transfer of rot-causing organisms that can "swim" in water from one plant to another, the so-called "water molds".
The safest bet is probably to "park" plants in a tub of dampened potting mix or sand until they can be planted in their permanent position. Not necessarily much easier after a face-planting than actually planting them in the ground, though. Mystlw hope you feel better soon.
