Kvesic added to England squad
Uncapped Worcester back-row Matt Kvesic was among three players added to England's Six Nations on Sunday as injuries took a toll of several of coach Stuart Lancaster's original selections.
Also summoned were Harlequins wing Ugo Monye and Saracens lock Mouritz Botha who both won the last of their England caps in November, against Fiji and South Africa respectively.
Kvesic joined what is now a 34-man squad on Sunday as injury cover for Exeter's Tom Johnson (knee) while Botha is due to arrive on Monday in place of Northampton's Calum Clark (shoulder).
Both Johnson and Clark, who were injured during weekend European Cup ties, will remain at their clubs for treatment, according to a Rugby Football Union (RFU) statement issued Sunday.
Monye will join the squad as cover while players who were in European Cup action are assessed by the England medical team.
England begin their Six Nations campaign at home to old rivals Scotland at Twickenham on February 2, with Lancaster's men looking to build on their shock 38-21 home win over world champions New Zealand last time out in December.
