Okafor was due to sign for Leipzig on-loan with an option to buy.
However, an issue was found in his medical, says TMW, which would have ruled out Okafor from making an immediate contribution.
Leipzig management had insisted Okafor be available immediately for selection and the issues discovered saw them pull back yesterday.
It's been suggested a calf strain has been the issue for Okafor and Leipzig's medical team.
