Aberdeen's attacking issues have worsened again after scans showed Fraser Hornby has suffered a bad thigh tear.
The striker was one of three loan signings that bolstered Aberdeen's forward line on deadline day following the departures of six other attackers in January and a major injury blow to Ryan Hedges.
The club wrote on Twitter: "Upon further investigation a scan has shown Fraser has suffered a significant tear on his thigh that will keep him out for a period of time."
The Scotland Under-21 international went off 20 minutes into Saturday's Scottish Premiership clash with Kilmarnock, five games into his loan spell from Reims.
His replacement, on-loan St Johnstone striker Callum Hendry, headed home Aberdeen's first goal in seven games with his first touch to earn the Dons a 1-0 win.
