"I'm disappointed and frustrated because I feel it was another game we should have won." said Ferguson.
"We got a lucky break with our goal at the end, but had some great chances before that.
"If Craig Mackail-Smith had taken his early opportunity it would have been a totally different match. No opponents like chasing games against us because of our pace on the break.
"Bristol is a difficult place to visit and we would have taken 1-1 before the game. Their home record is very strong so it is a good result for us in a way."
