Harlequins youngsters Ross Chisholm and Luke Wallace will be upgraded to the senior squad from next season after signing first team contracts keeping them at the Stoop until June 2013.

The pair - products of the Quins EPDG system - have made big steps since making their first team debuts against Newcastle last season in the LV= Cup.

Chisholm already has seven appearances and three tries under his belt and he is out for more as he pushes Mike Brown for a starting berth at full-back.

“I am delighted to have been offered the chance to continue my career at Quins, a club which is close to my heart having come through the school boy ranks," he said.

"Quins play an exciting brand of rugby and I am looking forward to pushing for a first team spot”

Open-side flanker Wallace is already pressurising the established Quins back row for a starting spot, after making his first competitive start for the club against Newcastle this season.

Wallace has progressed through the EPDG system and has also made seven appearances for the first team.

“I think the club is in the right place and I am really excited about the next few years with Harlequins," he added.

"I want to continue to push Will Skinner and Chris Robshaw for the number 7 shirt, but also to keep learning from him and all the senior players.

"It is such a positive environment and I am looking forward to the group pushing for silverware.”

Harlequins Academy Manager, Tony Diprose, added: “Both Luke and Ross have already shown huge potential in the rugby opportunities they have had at a young age.

"They are a credit to their parents, school, teachers and coaches back in Sussex, in both their work ethic and attitude.

"I look forward to them emulating recent Academy graduates Joe Marler and George Lowe in establishing themselves as first team regulars."
