Rev. Lett. {\\bf 96}, 246801 (2006)] proposed the most efficient deterministic teleportation protocol $\\cal T$ for electron spins in a semiconductor nanostructure consisting of a single and a double quantum dot. However, it is as yet unknown if $\\cal T$ can be completed before decoherence sets in. In this paper we analyze the detrimental effect of nuclear spin baths, the main source of decoherence, on $\\cal T$. We show that nonclassical teleportation fidelity can be achieved with $\\cal T$ provided certain conditions are met.
