So add Markham to list and one more unknown.
"For those trying to keep track of UFC injuries in the last few days, here is a partial list: Carlos Condit (cut hand from sheet metal slicing it as he was cleaning his garage), Dong Hyun Kim (knee), Tim Credeur (ribs), Rory Markham (torn Achilles tendon), Tyson Griffin and there’s one other semi-major show who is hurt that we haven’t found out yet (there are six in all)."
