Lengthy lay-off for England scrumhalf
INJURY UPDATE: Ben Youngs has now been ruled out for the remainder of England's Six Nations campaign after suffering a knee injury in the champions' opening victory against Italy.
The Rugby Football Union (RFU) confirmed the 28-year-old had ruptured the medial collateral ligament in his left knee, bringing an end to his tournament.
Youngs will undergo a further assessment with a surgeon later this week, but the RFU said he could be sidelined for up to four months.
Coach Eddie Jones called up Saracens' Richard Wigglesworth as a replacement, with England facing Wales at Twickenham on Saturday.
The news is also a huge blow to the Tigers, who are struggling in the bottom half of the Premiership.
