Harlequins players Joe Marler and Joe Trayfoot have been named in a 32-strong England U18 development squad to tour Argentina this summer.

Richmond College student Marler and Epsom College's Trayfoot helped England to a Grand Slam of victories in last month's Six Nations Festival in York. The squad will play games against Mendoza, Tucuaman, Buenos Aires before an international test against Argentina on their tour from July 14 to August 16. England U18 coach John Fletcher said: "This is my first experience of working with the U18s and I'm really looking forward to spending a concentrated period of time with them. "I have seen all the Under 18s games this season and I have been very impressed. They are clearly a very strong squad."
