St Mirren boss Stephen Robinson revealed Jonah Ayunga is out for the rest of the season with a cruciate ligament injury.
The 25-year-old Buddies striker sustained the injury after coming on as a substitute in the 1-0 cinch Premiership win over Motherwell last Saturday, and scans confirmed he will be out for at least six months.
Ahead of the home game against Hibernian on Saturday, Robinson said: “Two days ago we got bad news on Jonah. He has done his cruciate ligament so he is going to be a minimum of six months.
