Scotland have been dealt an injury blow ahead of the Autumn Nations Series with Saracens' back-row Andy Onyeama-Christie suffering a serious ankle injury. 

The 25-year-old sustained the injury in the sixth minute of his club side's Gallagher Premiership clash with Harlequins at The Stoop on Sunday. 

Play was paused for several minutes before Onyeama-Christie was stretchered from the field, with some of his team-mates in clear distress after witnessing the injury, which he suffered after getting his leg caught in a tackle. 

The flanker had started the season in good form for Saracens and would likely have been part of Gregor Townsend's Scotland squad for the four matches at Scottish Gas Murrayfield next month. 

Onyeama-Christie, who has eight caps, was excellent in the Six Nations, particularly in the defeat to Ireland in Dublin, but he missed the summer tour after breaking his arm towards the end of the Premiership season.
