ENGLAND prospect Jack Walker has signed a new deal with Harlequins as he closes in on making his international debut.

The 26-year-old is in his second season at Twickenham Stoop, where he has been a mainstay of the front row.

Having toured Australia under Eddie Jones last year, he is on course to win his first cap in the Guinness Six Nations opener against Scotland on February 4 as England contend with an injury crisis at hooker.
