Annoyingly, it's not on the YouTube highlights, but Sheffield United's Billy Sharp got away with a clear punch on a Luton player at Bramall Lane yesterday in full view of the referee (It was on the EFL Highlights show on ITV last night, if any clever techie can find it).
Interestingly, it was the same referee (Leigh Doughty) who Sharp criticised after the Sheffield United v Wrexham game recently, for which he was charged by the FA.
