Mako Vunipola faces a nervous wait to discover whether or not he can play any part in England's three-Test tour of New Zealand.
England boss Stuart Lancaster confirmed the Saracens prop will receive the results of a scan on his knee on Tuesday, shedding light on damage sustained during Saturday's 23-6 Heineken Cup final defeat to Toulon.
Lancaster admitted Saracens believe fly-half Owen Farrell has more chance of making Saturday's Aviva Premiership final than loosehead prop Vunipola.
England's head coach has refused to rule Dylan Hartley out of the New Zealand tour, despite the Northampton hooker still fighting to beat shoulder trouble in time for the Premiership final.
"Mako has a scan today and we'll see how it plays out in the next 24 hours," Lancaster said after naming an initial 30-man squad to fly out to New Zealand on Tuesday.
"I think Saracens are more optimistic about Owen than they are about Mako, but we'll have to wait and see.
"We've named four hookers so far, but we've not ruled Dylan Hartley out yet.
"We want to give him the flexibility and the opportunity to go on the tour."
