Someone who is better at math can fact check me here but…
Assuming you can win $1000 with your CIN/SF bet (must be quite long odds for that matchup):
Bet $500 total, on the other three outcomes.
KC/LAR $250
KC/SF $150
CIN/LAR $100
There’s a lot of unknowns here like how much your original bet is, at what odds, and the odds for each remaining possible match-up. Good luck with it.
Or…. keep it simple and let it ride. Esp if it was a cheap buy-in for the CIN/SF ticket.
