RICHIE Gray has pulled out of the Scotland squad for this summer's tour to the Americas through injury. 

The Toulouse lock is struggling with a hip problem and has been sent back to his club to continue his rehabilitation.

No replacement will be added to Gregor Townsend's squad, which includes six uncapped players as a number of established stars were rested. 

The three-match series begins next week with a game against Canada at the Commonwealth Stadium in Edmonton. 

Scotland then face USA in Houston on Saturday 16 June before completing the tour against Argentina at the Estadio Centenario in Resistencia a week later.
