Crewe Alexandra have held Leyton Orient to a goalless first half at the Alexandra Stadium in League One.
Russell Slade's men, who can potentially move back into the top of England's third tier with a victory today, were frustrated by their Cheshire counterparts in their bid to open the scoring.
The visitors fashioned the first opportunity of the encounter on 13 minutes when Kevin Lisbie raced through one-on-one with Crewe goalkeeper Ben Garratt, but the veteran forward was denied by the 19-year-old.
Orient missed another opportunity late in the half to break the deadlock, with Moses Odubajo heading narrowly wide of the mark from Dean Cox cross, which proved to be the last chance of the opening 45 minutes.
