Identify this frog? hurt leg?

[hmanget]

i'm a relatively experienced frog owner i have 3 tree frogs and other lizards. i was at the pet store buying my 3rd tree frog when the worker asked if i wanted this other frog that our crabs go a hold of(i don't know how). anyways, i THINK he is a southern leopard frog (i live in georgia). i just want a second opinion on what he might be. AND is there anything i can do to help his leg heal? hopefully it will on its own but is there anything i can do to help?

Thanks!
