Connacht coach Michael Bradley is sweating on the fitness of props Brett Wilkinson and Robbie Morris for Friday's Magners League clash with Cardiff Blues at the Sportsground.
Ireland hopeful Wilkinson and former England international Morris have been named in a 24-man squad despite the pair missing the trip to Edinburgh through injury.
Of that 62-13 defeat, the former Ireland scrum-half said: "The performance in Edinburgh was unacceptable. It was an embarrassing result and we need to respond quickly to it.
"We have been working hard all week to eliminate the errors from our play."
Bradley has been emphasising the importance of discipline to his players as the westerners have had four players sin-binned in their opening two games.
"We do not want to experience being down to 13 men again. If we continue to hand an advantage to the opposition we will be punished.
"The DVD of the Edinburgh match made for some very unpleasant viewing. Hopefully the crowd will get behind us this weekend and lead us to a good result."
