Scans and x-rays last week revealed that the Slovenian midfielder had fractured a bone in his right foot, an injury sustained in the 1-0 victory against Norwich last month but one which he played on with for three weeks despite the pain getting worse.
It means Koren will now miss some key Barclays Premier League games but while that is almost as painful as the injury itself, the Tigers captain remains upbeat.
“Yes it was bad news to get but hey, this is football and this kind of thing can happen,” said Koren.
“I’ve always been a strong and positive person and that is how I will stay. I have already started the hard (recovery) work and I want to be ready to play again as soon as possible.
“I’m going to be in every day doing my gym sessions. It will be hard but I know I am strong enough to get through it. I’m ready to work hard and I’m very positive about this.
“I have to also say that our fitness coaches are really good with us. They always know how to turn the exercises around so you know what you’re getting out of it.”
The injury means that Koren has already had to watch last weekend’s win at Newcastle and last night’s League Cup game against Huddersfield from the stands and while watching from the sidelines isn’t his forte, the 33-year-old will continue to support his team-mates and help out wherever possible whilst injured.
“I was in this situation at the end of last season as well and it’s really hard,” added Koren.
“You can’t enjoy it because you want to be out there on the pitch to help your team-mates. I’ll be around them every day and of course I will be there on matchdays too to support the lads. It means being involved in a different way for a few weeks but I will be there to wish the lads luck.
“We can take a lot of positive things from the first five league games and there is a lot of confidence in the team. Hopefully the results and points will keep coming.”
