BAGSHOT, England, March 16 (Reuters) - Winger Anthony Watson and number eight Billy Vunipola will both start for England in Saturday's Six Nations showdown with Ireland in Dublin after being selected by Eddie Jones on Thursday for their first starts of the championship.
Vunipola, who has come off the bench in the last two games following his recovery from a knee injury, starts in place of Nathan Hughes, while Watson, who entered the fray early against Scotland last week for the injured Elliot Daly, comes in on the right wing for Jack Nowell.
Daly has passed his concussion protocols and is fit to start on the left wing while Hughes and Nowell join an otherwise unchanged bench.
Victory will secure back-to-back grand slams for England and take their winning run to a tier one world record of 19, overhauling New Zealand's run of 18 from 2015-16.
