The centre-back has not played for the Scottish Premiership side since January.
Jozo Simunovic is hoping that he will be back playing for Celtic's first-team by August, and explained that he was playing with a fractured bone in his leg for a month-and-a-half, The Scottish Sun reports.
The Hoops have been without the 21-year-old since January, and while the likes of Erik Sviatchenko, Dedryck Boyata and Charlie Mulgrew have done well at the heart of the side's defence, Ronny Deila's men have arguably missed the talented Croatian.
And while he seemingly confirmed that he will not be playing for Deila again, he suggested that he will not miss too much of next season, before explaining the astonishing reasons why he carried on playing for over a month practically with a broken knee.
"I hope I will recover for August. I played when I was injured for a month-and-a-half with a fractured bone in my right knee," he told The Scottish Sun.
"I know it seems weird that I could play with this injury. But everything was down to psychology and the atmosphere on the pitch was phenomenal."
"I wanted more and more. When you play for a great club like Celtic you can play even with a fractured bone," he added.
While the Bhoys will have been boosted by the news that he will be back not long after the start of the next campaign, the news does mean that he will miss the club's opening Champions League games.
And given that they have struggled to make an impression in Europe in recent years, Simunovic's absence will be a major blow to the club's chances of making progress on the continent once again.
But given how the youngster managed to carry on playing for so long with such a considerable injury, it seems that if there is any player in the Hoops squad that will find a way to get back playing as quick as possible, it will surely be Simunovic.
