Wasps duo Matt Mullan and Elliot Daly will be out for three months and three weeks respectively after sustaining injuries in the victory at Northampton at the weekend.
Prop Mullan and centre/winger Daly underwent scans for further assessment.
“The club can confirm that Matt Mullan has torn a tricep tendon which will require surgery. It is unfortunately anticipated that he will be side-lined for approximately three months,” read a statement on the club’s official website.
“Elliot Daly suffered a grade two MCL tear (Medial Collateral Ligament – knee). The club will continue to treat him this week and assess how the injury settles. He is then expected to undergo a two to three-week period of rehab.
“The pair will remain with Wasps to follow the rehab schedule with the club’s medical team, who will keep in regular contact with the England medical team.”
Daly has been withdrawn from the England squad for the upcoming November internationals and replaced by Bath flyer Semesa Rokoduguni.
