Leyton Orient slumped to an emphatic defeat to Nottingham Forest but their League One status is secure after Bradford lost at Chesterfield.
Orient went ahead when Matthew Lockwood fired home Donny Barnard's neat pass.
Forest equalised when Jack Lester drove his shot low past Glyn Garner before Kris Commons put Forest ahead following a quickly taken free-kick.
And when Commons lofted a free-kick over Orient's defence, Lester pounced to ensure the points.
