The construction Aの、Bのと is used to enumerate statements.
He makes all kinds of excuses; that his feet hurt, he has caught a cold or he has a headache.
Here three excuses are enumerated by him not to participate in the practise. One might chose, however, to mention his (supposedly) hurt feet and omit other lame reasons (ellipsis). In keeping with the general form required in the construction, the ellipsis is expressed by nan-no.
In toto, Nicole, your question sentence means, "He always skips practises, making excuses on hurt feet or something."
