The UFC announced last night that Bruno Santos was out of his fight at UFC 175 against Chris Camozzi and Trevor Smith has agreed to replace Santos against Camozzi. 
However, UFC officials announced on Friday afternoon that the fight between Camozzi and Santos is still happening at UFC 175 and Smith will now meet Tor Troeng at UFC Fight Night Dublin.
UFC Fight Night Dublin will come from the O2 Arena and will be headlined by a featherweight bout as Conor McGregor meets Cole Miller.
Smith (11-5) has dropped four of his last six fights and has gone 1-1 in the UFC. After winning his UFC debut earlier this year, he returned in January at UFC Fight Night 39 and was defeated by Thales Leites.
Troeng (16-5-1) was a member of Team Sonnen during The Ultimate Fighter 17 and won his official UFC debut against Adam Cella. He would drop his next fight in the UFC against Rafael Natal in September and this will be his first fight since the defeat.
