Stoke forward Bojan Krkic has been ruled out for the rest of the season with a serious knee injury.
The 24-year-old suffered cruciate knee ligament damage in Monday's 4-1 FA Cup fourth-round win at Rochdale, after scoring the opener.
Scans have revealed he suffered a ruptured cruciate ligament in his left knee and will have to undergo surgery.
Manager Mark Hughes told the club's official site: "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. We wish him a speedy recovery."
