INJURIES to three key players are giving Orient boss Russell Slade a headache.

Adam Chambers was hauled off with a sore calf during the first half of Orient’s 2-1 friendly defeat to Blackpool, on Saturday.

He joins in the sick bay other first team regulars, Ben Chorley (calf) and Charlie Daniels (knee ligaments.)

Chambers is expected to recover soon. Chorley could feature in action against Spurs on Wednesday.

But Daniels is unlikely to play against the Premier League club at which he began his career.
