England's Churchill Cup squad has been reduced to 25 following the withdrawal of Sale back row Magnus Lund with a thigh injury.
There will be no replacement for Lund as Newcastle's Phil Dowson was called up as cover last week when Saracens number eight Hugh Vyvyan was ruled out of the trip to Canada, also through injury.
England coach Joe Lydon has made no further changes to the squad - captained by Worcester openside Pat Sanderson - which was due to depart for Toronto on Thursday before relocating to Edmonton the following Wednesday.
England squad for the Churchill Cup matches against Canada and the United States: Backs: C Bell, A Erinle, A Gomarsall (vice captain), A Goode, A Higgins, U Monye, P Richards, P Sackey, J Simpson-Daniel, M Tait, S Vesty, T Voyce.
Forwards: G Chuter, L Deacon, P Dowson, J Forrester, P Freshwater, S Hooper, C Jones, L Mears, R Morris, T Palmer, P Sanderson (captain), M Shelley, S Turner.
