Yeah, Rijker wanted the fight, Martin didn't. Rijker retired because she couldn't get the fight. After she came back from retirement they had it lined up but Rijker tore her achilles. Since Martin was so clearly fading Rijker said she would only return to the ring to fight Ali. While Rijker was much much better than Ali she faught at 140 and Ali at 168 so it would have been a mismatch size wise.

I don't worry too much that Rijker never got to beat up Martin because it would have been easy.
