ORIENT will not have to deal with Posh top scorer Craig Mackail-Smith tomorrow night (Tuesday).

The 11-goal hitman is banned after his fifth yellow card last weekend.

But ex-O Aaron McLean could pose a threat at London Road with three goals in four games by him.

Winger Lee Tomlin could push inside from the flank as a second striker.

Definitely out for the hosts are hitman Dave Hibbert (knee) and Lee Frecklington (ankle).

A groin problem sidelines Tommy Rowe.

Woeful defending and a string of recent defeats means out-of-form Posh currently have the worst goals-against tally in League One.

Now the axe hangs over boss Gary Johnson.

Chairman Darragh MacAnthony this week hinted Johnson will be sacked unless results improve over the next five games.

Former Orient defender Gabriel Zakuani could feature tomorrow.

He has struggled for regular football since his £1m move from Orient to Premier League Fulham, in 2006.

Zakuani has played eight league games for Peterborough so far this season.
