Harlequins has confirmed an exciting group of pre-season fixtures as it prepares for the start of the 2013-14 season.
Roland Mercer

The former England U20s winger enters Saturday's game in a rich vein of form with five tries in his past two games and 14 tries in all this season, already bettering his total of 12 in 2010-11.
The former England U20 international was shortlisted for Try of the Season at last season's Guinness Premiership Try of the Season awards and his searing pace has continued to cause problems for opposing defences this season.
A product of the Gloucester Rugby Academy, he has shown his versatility by also turning out at full back and must be pushing hard for a Saxons call up.
Eliota Fuimaono-Sapolu
In his second season with the club, Eliota has established himself as one of the pivotal figures in the Gloucester Rugby line up.
The Samoan international centre joined Gloucester Rugby from local rivals Bath Rugby in the summer of 2009 and quickly established himself as a fans' favourite in his first competitive appearance which was against his former club.
There is more to his game than just smashing the ball up the middle. He has an eye for a gap and handling skills which are the envy of many a Premiership player including helping to create and finishing off a sensational try in last weekend's LV= Cup Final.
Luke Narraway
27 year old Luke Narraway has enjoyed a season to remember with Gloucester.
Following a disrupted 2009-10 season due to a back surgery, the back row forward has returned to the form which saw him achieve senior England honours.
An England Saxons tourist for the past two summers, he has captained Gloucester with distinction in the absence of Mike Tindall, combining leadership skills with a series of impressive personal performances.
'Naz' had the honour of lifting the LV= Cup trophy last weekend following the 34-7 win over the Newcastle Falcons and will be a key figure as Gloucester press their Aviva Premiership play off claims over the next few weeks.
Nick Wood
Swindon born Nick Wood has been an unassuming but massively effective presence in Gloucester's front row this season.
Another Saxons tourist on the successful Churchill Cup campaign in the summer of 2010, he has been a rock in the Gloucester scrum and already made more than 20 appearances so far this season.
His consistency has seen him desperately close to full England honours and he was denied a full cap only by illness in South Africa.
His international claims are frequently lauded by the Gloucester Rugby coaching staff and such recognition would be long overdue and well deserved for a man who has made more than 150 appearances for Gloucester.
