Derry City suffered a huge injury blow on Monday night after the club confirmed Michael Duffy is set for a spell on the sidelines.
The flying winger made his second debut for his hometown club as a 61st-minute substitute following his high-profile move from Dundalk.
But Duffy was injured in a tackle with Keith Cowan and forced to limp off less than 10 minutes after his introduction in the 2-0 win over Drogheda United.
