What kind of spider is this?

The other day I killed the biggest spider I’ve ever seen in this area. I walked into the shed, saw it, and ran away like a little girl. It ran under the lawn mower, but I still sprayed him with some good bug killer. After I was convinced he was dead, I scooped him up and put him in a ziploc. 30 minutes later the legs started folding back out like he was coming alive:uhh: The whole bag went in a mason jar. Looked like that Brown recluse but darker, but I was told it was not. I still sprayed some chemicals in there and shut the door. Fuck spiders.
