England winger David Strettle was injured scoring a fourth-minute try as Harlequins and Scarlets opened their LV= Cup campaign with a hard-fought 15-15 draw.

Strettle, released to play for his club when Martin Johnson reduced his original 32-man squad for the Twickenham clash with Australia to the match-day 22, continued briefly after treatment.

But clearly struggling, he was replaced by George Lowe nine minutes later in his side's opening pool match at The Stoop.

Harlequins added a further try from lock George Robson and a penalty and conversion from fly-half Rory Clegg.

The Welsh side replied with tries from centre Gareth Maule, left-wing Andy Fenby and a penalty and conversion from number 10 Rhys Priestland.
