Mark Hudson admits he's at a loss to explain the decision behind Callum Robinson's disallowed goal during the defeat to Coventry City on Saturday.
Robinson thought he'd cancelled out Viktor Gyokeres' first-half opener at the Cardiff City Stadium just after the interval, controlling a Joe Ralls header with his back to goal before turning to fire home.
But referee Bobby Madley, after consulting his assistant, deemed the Republic of Ireland international to be offside, disallowing the goal.
