Brentford striker Gary Alexander has been ruled out for the rest of the season after undergoing knee surgery.
The 31-year-old, who has hit 12 goals for the League One club this season, has missed the last three weeks.
The Bees are struggling with injuries with keeper Richard Lee, centre-half Pim Balkestein and forward Charlie MacDonald all ruled out for the season.
Defenders Craig Woodman, Leon Legge and Karleigh Osbourne are all doubts for the last two games.
Osbourne had to go to hospital following Monday's draw with Notts County after Craig Westcarr's powerful shot struck him in the face.
