I would lay 10 to 1 you'll get paid, although they may have a few words with you first. The reason I have some doubt is a sports book can rescind a wager that was obviously made in error, with permission of the Gaming Control Board.
"A book may not unilaterally rescind any wager without the prior written approval of the chairman." -- Nevada Regulation 22.115
While this right exists, based on anecdotal evidence, it is very seldom invoked. Let me know what happens.
p.s. I was notified later by the questioner that he was paid without much trouble.
