Harlequins defend their London Floodlit Sevens title at Rosslyn Park tonight (Wednesday).

The tournament starts at 5pm when the Fijian stars of the Army play Cambridge University.

The tournament comprises four pools of three teams, playing in a round-robin format to produce the four semi-finalists.

Pool A: Richmond, Army, Cambridge University. Pool B: Rosslyn Park, London Irish, Oxford University. Pool C: Saracens, London Welsh, London Scottish. Pool D: Harlequins, Esher, Loughborough University.
