Stuart Hogg is fit enough to be included in the Scotland squad for Saturday’s home Test against Fiji.
The star full-back, 26, was expected to miss the entire autumn series after ankle surgery in September.
Hogg’s Glasgow Warriors team-mates Adam Ashe, Scott Cummings and Nick Grigg are also called up after last Saturday’s defeat by Wales in Cardiff.
English-based duo Josh Strauss and Duncan Weir return after long absences from the international scene.
Forwards coach Danny Wilson refused to rule out the possibility of Hogg making a remarkable comeback against Fiji, having not played since injuring his ankle against Munster on 7 September.
“He’s still got a few boxes to tick, [there are] a few decisions to make on that,” Wilson said. “But he’s made really good progress and he’s ahead of schedule so we’ll see how he is in the rest of the week.”
Sale Sharks back-row Strauss has not featured under head coach Gregor Townsend since a defeat in Fiji on the summer tour of 2017, while the last of Worcester Warriors fly-half Weir’s 27 caps came as a replacement against Italy in last year’s Six Nations.
Scarlets back-row Blade Thomson is denied the chance of a Scotland debut after suffering concussion during Friday’s Pro14 loss to Edinburgh at Murrayfield.
Centre James Lang, a late squad call-up for the opening loss to Wales, picked up a rib injury playing for Harlequins.
Leicester back-row David Denton and Edinburgh centre Matt Scott miss out again as they continue their ongoing recovery from head injuries.
Edinburgh trio Ross Ford, Henry Pyrgos and Dougie Fife have been released from the squad.
