UFC featherweight champ Jose Aldo had an unexpected visit with doctors this week unrelated to any action inside the Octagon. Already nursing a broken foot from his bout with Chan Sung Jung at UFC 163, Aldo is now dealing with kidney stones.

An initial report from UOL was confirmed by MMAFighting where a UFC physician was cited as saying he’d been led to believe the issue wasn’t serious and was something Aldo had dealt with before.

Aldo’s stint in the hospital should be a short one. However, his time on the sidelines will likely extend into 2014 based on the damage done to his foot from an errant kick in the opening round of last weekend’s effort.
