Scotland international Allister Hogg has boosted coach Matt Williams ahead of the RBS 6 Nations opener against France on Saturday.
The Edinburgh Gunners player was rated doubtful for the game in Paris due to a knee injury.
But, after returning to full training with the Scottish squad on Monday, Hogg has impressed national team doctor James Robson, who said: ''He is doing well and will be monitored further to see if he has any reaction to the training on Tuesday.
''However, we are delighted with his progress.''
Glasgow Warriors scrum-half Graeme Beveridge missed training with a slight cold, while Northampton number eight, Ross Beattie, rested after the game against Sale Sharks on Saturday.
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.
