Colback was given the 'good' news that it was only going to be a six-week spell out injured, his longest injury lay-off since turning professional.
"Touch wood, I haven't had many bad injuires," said Colback.
"Before this, the longest I was out was four weeks, so this is the worst of my career so far.
"I suppose I've been lucky, when you look at other players and what they've been through, but you can't prevent injuries - it's part of the game - so you just have to get on with it.
"Every player is the same when they get injured - they don't want to be in the treatment room. You never want to miss any games but I'm just trying to look at the positives that it could have been a lot worse.
"Right now I'm just resting to help the knee heal, and once that stage is out of the way I will be doing rehab before trying to get outside again as quickly as I can.
"It's worse watching matches from the stands. From my experience, it's a lot easier playing than watching.
"It will be a tough few weeks but the team are playing well and hopefully we can start turning those performances into victories," he told the club's website.
