From a cursory examination, it looks like a common wolf spider. Nothing to really worry about.
They look really nothing like a brown recluse which has thin spindly legs and often times look more tan than brown. Kansas is thick with them though. I've been bitten twice by recluses (both in woodshop class in high school). The first was really bad, necrosis in my leg, bad swelling and blood poisoning from just above my knee down. Reflecting on it later I realized I'm lucky to still have a leg. That being said, I grew up in a farm house that was full of them and was never bitten once while on the farm.
Still don't like em.
