Luke Marshall (chest) and Iain Henderson (concussion) sustained injuries during Saturday's Heineken Champions Cup match against Stade Rochelais at Stade Marcel Deflandre. As a result, both players will be unavailable for this week’s home game against Sale Sharks.
Jake Flannery is also currently unavailable for selection having sustained a hamstring injury during training last week.
Billy Burns suffered a calf injury during the pre-match warm-up in La Rochelle. His fitness for selection this week will be monitored through the coming week.
