Gray, who won his 57th cap at the weekend, is another big loss to Gregor Townsend's men, who have been without influential fly-half Finn Russell for the opening two rounds of the championship.
Russell's international future is in doubt after he revealed a breakdown in relations with Townsend.
The Scotland coach is badly in need of a result when his side travel to face Italy on February 22 after back-to-back defeats to start the Six Nations.
Townsend was already under pressure after Scotland crashed out of the World Cup at the group stages in Japan late last year.
