The Spaniard joined the club from Barcelona in a €4 million summer deal and had set about revitalising his career, making a significant impact at the Britannia Stadium after sealing his move.
Bojan has scored five goals in all competitions and netted a brilliant strike against Rochdale on Monday, though he had his game prematurely cut short when he pulled up short at Spotland Stadium, before reports suggested that he had left the ground on crutches.
And, after undergoing a scan, the club have confirmed that he will miss the remainder of the 2014-15 season, with manager Mark Hughes quickly moving to lament his loss.
"It's bitterly disappointing for the club but even more so for Bojan himself as he was making such a big impact on the Premier League and clearly enjoying his football," he told Stoke's official website. "We wish him a speedy recovery."
Stoke are currently 10th in the Premier League, having taken 29 points from 22 games.
