Exeter captain Chris Curran is waiting to hear the extent of his Achilles injury.
Curran will miss the remainder of the season after sustaining the problem against Bury at the weekend.
And he is now waiting to hear whether he has ruptured his Achilles tendon.
"It sounds like a ruptured Achilles and if it is, that's probably the worst injury you can get in football," Peters told BBC Radio Devon.
"I do feel for Chris. He won't play again this season."
