Prop Cian Healy is expected to miss the start of the 2014 RBS 6 Nations after undergoing surgery on his injured ankle on Wednesday.
Leinster 'A' enjoyed a fine 47-18 victory over Leeds Carnegie in their cup opener, and this week Noel Reid moves to full-back in place of Darren Hudson who injured his shoulder in the last minutes of the Leeds game.
John Cooney will partner Cathal Marsh at half-back, with Collie O'Shea continuing his centre partnership with Brendan Macken.
Up front, Ruddock joins Jordan Coghlan and Leo Auva'a in a strong back row trio, while Martin Moore starts at tighthead prop in a front row which features Tom Sexton and skipper Jack McGrath.
