Fears over the fitness of Harlequins star David Strettle has led to team manager Martin Johnson calling Paul Sackey into his England squad.

Strettle has not fully recovered from a rib injury sustained in the LV Cup a week ago and is being assessed by both the Quins and England medical teams.

He had been sent back to Quins as one of 10 players allowed to return to their clubs because they were not going to feature in the games against Australia and Argentina.
