Urgent as it may be, I'd wait to hear from one of the more experienced members. However I am pretty sure that generally keeping wild caught animals of any species is not the best idea. Not just because they may carry bacteria/diseases, but because the frog is not used to having boundaries, or any of the other aspects of caged life, so it may not react well to being in confinement.
In my area of the country the only things that are present the opportunity to be caught are standard American toads, or the occasional bullfrog. I'll usually catch them put them in a temporary viv, snap some pictures and throw in a few crickets, then let them go. The longest I have ever had a captive animal was a week or so (bullfrog) and it wanted no parts of it. I kept him until I could take him far away from my house as he kept jumping in the pool, and I'm thinking chlorine is no bueno for frogs.
Hope this helps.
