"He'll miss the Six Nations' Championship," David Jordan, Glasgow's chief executive, reported today. "We probably won't see him again in the Celtic League this season."
Glasgow's last scheduled league game is against Leinster at Hughenden in mid-April, though Celtic Cup games follow later that month and in May.
Three other Glasgow players, Rory Kerr, Sam Pinder, and Colin Gregor, are having operations this week. Rory is having a knee operation following injury last month whereas the two others are having groin surgery.
