Paul Townend replaces Ruby Walsh on Faugheen© Photo Healy Racing
Vroum Vroum Mag is a late withdrawal from the Unibet Morgiana Hurdle at Punchestown.
The multiple Grade One-winning mare, trained by Willie Mullins, will miss the big race as she is lame.
A field of four will now go to post, headed by her stablemate Faugheen who is set to have his first race since January 2016.
He will be ridden by Paul Townend in the absence of injured jockey Ruby Walsh.
