Walker has honours with Wales at Under-18 and Under-19 levels

Dragons scrum-half Alex Walker has joined London Welsh on a loan deal, one of seven new recruits at the club.

Newport-born Walker, 22, has made 29 appearances for the Dragons, and has gained honours with Wales at Under-18 and Under-19 levels.

He could form a half-back partnership with Aled Thomas, who moved from the Dragons earlier in the summer.

Nick Runciman, Darrell Ball, Tom Audley, Tom Rock, Pete Murchie and Ed Lewis-Pratt also join the Exiles.
