Saracens flanker Andy Onyeama-Christie has been ruled out of action for the rest of the season with a fractured arm.
His club have said he will play no further part in the current campaign, which concludes in June.
The injury also puts the 10-time capped Scotland international in doubt for the inaugural Nations Championships this summer. The national team face Argentina in Cordoba, then Fiji at Murrayfield in the new compeition in July.
For Onyeama-Christie, 27, it is the latest in a series of injuries in recent seasons, having twice previously broken his arm and also fracturing and dislocating his ankle.
He has played in 19 games for the London club this campaign and agreed new terms to extend his stay in February.
