The 30-year-old is expected to be sidelined for up to 12 months after he ruptured three ligaments in his right knee against Basel.
Vidic is to undergo surgery later this week, but Silvana Martina has been quick to deny any fears over his long-term future.
"The first forecasts say it can last for a year, but it is meaningless to talk about the end of his career," he is quoted as saying in the Daily Mail.
"It's a serious injury but club doctors assure us that the recovery will run smoothly and he will be back on the field.
"It will take time to get back into the old rhythm, but there is no doubt that Vidic will be his old self again.
"Nemanja is feeling good. He will be back next year stronger and better."
