Could the SEC be left out of the Playoffs?

If Alabama beats UGA, will a SEC team be left out?

Michigan beats Iowa IN
PAC-12 Winner IN
FSU beats Louisville IN
Texas beats Oklahoma State IN

Alabama beating UGA is least likely of the above, but if it happens, I think the SEC will get left out.

The only team that could potentially get bumped down with a win would be Oregon, but they are already higher ranked, so not sure how likely that’ll be if they beat #3 even if Alabama beats #1.
