Torquay United striker Ryan Jarvis could be out for two months after partially puncturing his lung in the 1-1 draw with Northampton.
The 26-year-old also suffered fractured ribs in the challenge but played on until the end of the game.
Jarvis, who scored Torquay's goal, was hurt in the final five minutes after a sliding challenge and left Plainmoor in an ambulance.
He had started the last four games and scored five goals this season.
