Quinn Mulhern (18-3) was hoping to rebound from a technical knockout loss in his UFC debut with a win at UFC Fight Night 32 .  The opportunity to capture his first UFC victory will have to wait for a later date. Mulhern was scheduled to face Thiago Tavares at UFC Fight Night 32 on Nov. 9, but an injury has forced the lightweight off the card.  Justin Salas has agreed to replace Mulhern against Tavares on short notice. UFC  officials confirmed the injury and opponent change on Friday
