I think boxing should introduce alternates as back ups for championship fights or big match-ups.

When a match is made the next 2 (4) available fighters should be included on the undercard. If one of the main event fighters pulls out for any reason, fails weight, PEDS, injured etc then one of the alternatives steps in.

This way the card still goes on, a weight cheat or PED abuser misses a payday (obviously they would need to be caught beforehand).

If the main event goes off as planned the alternates still fight and the winner(s) enhance their rating.

The alternates would need to be among the top 10 or so, higher if possible, so that if one of the main guys is dropped it is still an appealing fight.

Thoughts?
