Scotland lock Jason White intends to make his comeback from injury before the end of the RBS 6 Nations tournament.
The struggling Scots will be without the lock - probably his country's best player in the competition so far - for Saturday's Murrayfield clash with Italy because of a knee injury.
But the Sale Sharks player has targeted a return either against Wales at Murrayfield on March 13 or England at Twickenham a week later.
He told STV: "I'm aiming to be ready for selection for the Wales or England game.
"I would love to be involved. I'm going to work hard with the physios back in Sale and they are optimistic.
"It's not serious. It's a little bit swollen but thankfully two to four weeks is how long the physios are saying."
White, who won his 45th cap against Ireland earlier in the month, damaged his right knee in Sale Sharks' victory against Leeds Tykes last week.
Scotland team doctor James Robson confirmed the injury had not been as bad as it might have been.
He said: "Jason underwent a scan this morning.
"He has ligament damage and a little bit of bone bruising. Happily no surgery is required and he will embark on intensive rehabilitation as part of a two-to-four week recovery period."
Scotland coach Matt Williams, who will announce his team on Thursday, is already without concussion victim Ross Beattie. Glasgow's Paul Dearlove and Simon Cross of Edinburgh have already been called up as replacements.
Like Italy, the Scots have been beaten in their first two games in this year's tournament, losing narrowly in France before subsiding to Ireland.
England flanker James Haskell insists he will be pushing as hard as possible to be back from a toe injury in time to make his case for a spot in Eddie Jones' side looking to defend their RBS 6 Nations title next year.
