Torquay United defender Angus MacDonald says his season is over after injuring ankle ligaments in the Saturday's 0-0 draw at Nuneaton in the Conference.
The 22-year-old centre-back was stretchered off after an hour and taken to hospital, although he travelled back with the team.
"Safe to say my season is over," MacDonald posted on Instagram.
"Knock backs only make you stronger. Know the boys will finish the season strong," he added.

Torquay changed their system against Nuneaton, playing three centre-backs and two wing-backs.
They kept a clean sheet for the first time in six games, although they went a fourth game without scoring a goal.
Manager Chris Hargreaves told BBC Radio Devon: "Plenty of managers change system, we've conceded some goals recently and we changed it to have three centre-halves.
"I thought, apart from a couple of erratic five minutes, I was looking to their goal most of the time and that tells me it was a strong performance.
"We're not quite having that quality in front of goal that we did earlier in the season, we're just snatching at things, whereas before we might have that extra breath to have that quality delivery."
