is this a brown recluse?

I don't think it is but my wife thinks it is. I think it's a yellow sax spider

IMO...No, I don't believe it is a brown recluse. Missing the telltale dark violin marking.

No, not a Brown Recluse, agreed with Darth, no violin. Plus, it looks a bit bright in the abdomen, the recluse's I have around here have a light abdomen but not THAT light.

Thx guys I know tarantulas but nothing about true spiders.

Have a look at Reclusa. Notice the legs and how it walks. Their proportion to the body. They are a uniform brown without any markings and no visible setae. Then if you see the violin marking, it might be one. Your positive ID requires grabbing a magnifying glass and checking the eyes. 6 eyes in 3 dyads, the outer most pairs fused together.

if it helps its definedly not a recluse spider Im working with genus Loxosceles for years and out of the 99 specified species i cannot see real similarity's.
Recluse spiders are from the group Sicariidae and have six eyes, this little fellow has 8 eyes.
Altough seeing the violin shape on the cephalothorax isn't always the way to confirm its a recluse. I know species where the cephalothorax is very light and the marks are almost invisible.

And pre molt the violin may not be visible.

here's one shot of a recluse spider ( L.laeta )

reclusa not native to Utah. Lox deserta barely barely barely reaches extreme SW Utah

On a side note about how big was that spider?

Thx again guys I was 99% sure the spider in question is about the size of a dime with legs outstretched

well,, if you want to know something about the locality's, below listed the 99 subspecies.
as the climate gets warmer these spiders spread out trough country's where they don't belong.
but as told before this is not a recluse so your wife can safely go to sleep

but for the nonarachnoligists identifying a brown recluse spider is quite simple.
1 brown recluse spiders are Sicariidae ( six eyed ) and the spider in question has eight eyes.
2 Even younger specimens and freshly molted recluse spiders have a particular violin shape on the cephalothorax.
when the violin markings cannot be seen, you have to take a closer look from a different angle cause recluse spiders have 7 rows of hair on the cephalic range and these hairs show a recluse shape too.
There are lots of ways for identifying but from a distance like this, these points might help a little
