Scotland back-row Matt Fagerson has been ruled out of Friday's Guinness Six Nations clash with France after sustaining an ankle injury in training.
Edinburgh's Nick Haining will replace Fagerson at number eight for the visit to Paris.
Head coach Gregor Townsend has bolstered his squad by calling up Glasgow forward Ryan Wilson, who will be on the bench at Stade de France and could win his 50th cap.
"Matt suffered an ankle injury in our final training session this week before we headed to Paris," Townsend said in a statement.
"It is disappointing for Matt, who has been playing consistently well throughout the Championship.
"Nick now has the opportunity from the start to show his abilities in what will be a great challenge for our forward pack."
Scotland can still finish second in the Championship, while France will be gunning for the title.
Fagerson has remained in Scotland to have his injury assessed and will return to his club to begin rehabilitation.
Speaking about the inclusion of Wilson, Townsend added: "We were able to call on Ryan at short notice given Glasgow Warriors had already conducted two Covid tests this week which meant he was safe to travel and join up with the squad yesterday afternoon.
"Given Ryan's Test match experience and his form this season, we believe he will grab his opportunity on his return to the squad."
