London - Uncapped Gloucester centre Billy Twelvetrees is set for an England debut against Scotland at Twickenham on Saturday after being confirmed on Tuesday in coach Stuart Lancaster's 23-man match-day squad.
With powerful Leicester midfielder Manu Tuilagi out of England's Six Nations opener due to injury, Twelvetrees was selected ahead of London Irish outside centre Jonathan Joseph.
Meanwhile, Saracens wing David Strettle was also included in the match-day 23, meaning there was no place in the squad for Northampton fullback Ben Foden.
Lancaster is due to name his starting XV and eight replacements for the Calcutta Cup clash on Thursday.
