Leyton Orient will be without striker Paul McCallum for tonight's game at home to Carlisle United.

McCallum was stretchered off with a knee injury during Saturday's draw at Northampton Town but the club are still waiting to find out the extent of the problem. 

The O's will also be without Joe Maguire after the Liverpool loanee returned to the Premier League club having made one appearance for Orient.

Goalkeeper Alex Cisak will play tonight but then misses this Saturday's home game with Notts County due to international duty with Australia. 

Ian Hendon's side dropped off the top of League Two on Saturday after failing to win for the last four matches. Orient are now third in the table sitting one point behind leaders Portsmouth. 

Carlisle are the top scorers in the division and the mid-table side also have the most prolific goalscorer with former O's striker Jabo Ibehre netting eight league goals already this season although he is out with a hamstring injury tonight.

Orient will hope the team can continue their recent record against United with four consecutive wins. In each of those victories the O's have scored at least four goals.
