Scotland locks Cummings and Brown ruled out of Ireland Six Nations clash
Gregor Townsend's men scored seven tries in their stunning 50-40 victory over France at Murrayfield at the weekend, ending Les Bleus' dreams of a Grand Slam.
France remain top of the table on points difference ahead of their match with England in Paris but the second-placed Scots will head to Ireland with a chance of making history if Steve Borthwick's men can do them a favour.
Townsend has lost six players to injury for their final match of their campaign, including Brown, who has a calf injury, and Cummings, who has hurt his hamstring.
