The Great Ormond Street Hospital Children's Charity (GOSHCC) is the charity that will benefit from Big Game 5 when Harlequins take on London Irish at Twickenham Stadium, kick-off 2.15pm.

The four squad members were shown around various hospital wards and experienced first-hand the hard work that the nurses and staff of the hospital do as well as getting the opportunity to meet some of the patients.

Along the tour, the players joined in various activities with the children. Hopper played, and lost, on the Wii games console, while Evans became an astronomer while playing with toy rockets. The Harlequins mascot, Harley Bear was also on hand to meet the young children and donate clothes and a PlayStation 3 to the hospital from the club.

Speaking of the visit, Harlequins fly half Nick Evans said: "It's been very humbling to see the work that's being done with the children. What struck me is how positive everyone is in trying to get these kids better, everyone has smiles on their faces and we were also able to add to those smiles."

Echoing Evans' comments, Hopper said: "It is very eye-opening to see the work that the doctors and nursing staff do and the experiences that these children have. From a personal point of view I found it quite interesting and quite humbling. To see a smile on these kids' faces is something pretty special."

Tickets for the Big Game 5 are available and can be purchased through Ticketmaster. With tickets starting from just £10 this is festive season event not to be missed.

Harlequins have also launched a charity shirt for Big Game 5 which includes the GOSHCC logo. £5 from every shirt bought will go to the charity.
