Queens Park Rangers striker Andrew Johnson has been ruled out for the "majority of the season" with an anterior cruciate ligament injury.
Johnson, 31, picked up the knee problem during Saturday's 0-0 draw with Chelsea at Loftus Road and was forced off before half-time.
QPR manager Mark Hughes expressed his concern after the match and now a series of scans have revealed the full extent of the problem.
"Andy Johnson suffered an anterior cruciate ligament injury against Chelsea and is likely to be sidelined for the majority of the season,'' QPR posted on their official Twitter account.
Defender Fabio da Silva also suffered an injury but Hughes expects the on-loan Manchester United full-back to return from his hamstring problem in two weeks.
