There are six combinations by height - ABC, ACB, etc.  By Clues 1 and 3, they yield the following results for Older/Younger boxer:

ABC = BA
ACB = BA
BAC = AA
BCA = AC
CAB = BC
CBA = AC

The third combination above is eliminated since A can't be both.
The fifth combination is eliminated because per Clue 2, C cannot be younger than B while taller than B.

This leaves two possibilities for Older/Younger boxer:

BA  or AC

In both instances, the Younger boxer is also the Taller boxer:

BA -> ABc or AcB

AC -> CAb or CbA

So either:

B is Shorter and Older than A

or

A is Shorter and Older than C

Clue 2 says the shorter boxer can only be B or C.  Therefore, BA:

Cliff is not the boxer.
