Injuries wreck Eddie Jones' plans
SQUAD UPDATE: England coach Eddie Jones has been forced to replace three players from a pre-season camp.
A slew of injuries over the course of the weekend's Premiership matches wrecked Jones' plans.

In turn, Jones has called up George McGuigan, Adam Radwan and Jack Singleton respectively.
An RFU statement reads: "Jamie George, Guy Porter and Jack Walker have withdrawn from the England men’s squad through injury.
"England coach Eddie Jones has called up Newcastle Falcons duo George McGuigan and Adam Radwan, along with Gloucester's Jack Singleton, to the squad who have met today in London for a three-day training camp."
Those unavailable for selection due to injury include Alfie Barbeary, Nic Dolly, Alex Dombrandt, Charlie Ewels, George Ford, Jamie George, Sam Jeffries, Maro Itoje, Nick Isiekwe, Courtney Lawes, Guy Porter, Sam Underhill, Jack Walker, Anthony Watson.
