Mako Vunipola has been ruled out with a "significant" hamstring injury, confirmed Saracens Director of Rugby Mark McCall.
“Everybody else is ok”, allaying worries over Jamie George and Billy Vunipola, who also had slight injuries on Saturday evening, and Alex Goode, who spent close to 72 hours celebrating the final in his matchday kit.
“Mako has torn a hamstring and is waiting to see exactly what’s happened but I would very much doubt he’d play again this season,” McCall said. “Titi also won’t play again this season.
“He [Mako] won’t be out of the World Cup. He will be out for a while though, it is quite a significant injury.
“Obviously it’s disappointing to lose two players like that and it makes us a little bit vulnerable, to be honest.”
Vunipola missed a large part of the Six Nations following an ankle injury and then suffered another injury to the same joint that resulted in an aborted comeback.
His appearance at Newcastle's St James' Park was only his second match since the Six Nations win over France in mid-February.
