Cape Town - Harlequins and England flanker Chris Robshaw will find out on Monday whether he requires surgery on his shoulder.
Robshaw missed the Big Game against Gloucester back on December 27, then played against Worcester days later where his shoulder flared up once more.
The 30-year-old was a limited participant in England's training camp in Brighton and following a scan is now waiting for the verdict of a specialist to see whether he requires an operation.
"I'm seeing a specialist on Monday and will know a bit more after that," Robshaw told Press Association Sport.
"It's all up in the air at the moment and it's hard to know exactly where I stand. Once we get to Monday, we'll know the position we're in.
"It feels fine in everyday life but rugby isn't everyday life, that's the thing. It's got to be ready for rugby.
"We'll see if it settles down a bit before Monday and then take it from there and make a decision."
England are already set to be without Billy and Mako Vunipola for the opening game of the Six Nations against France, while lock George Kruis is a concern.
Joe Launchbury though has offered Eddie Jones a timely boost. The Wasps lock's calf injury is not as bad as first feared, according to Standard Sport, and he could return to face Toulouse in the Champions Cup on January 14.
