Crawley demonstrated they have almost got what it takes to compete in the Nationwide Conference after allowing Telford to come back from two goals down to claim a 3-2 win in the first round of the FA Cup.
The Dr Martens Premier Division side looked to be on their way to the second round after taking a 2-0 half-time lead through goals from Paul Armstrong and Justin Gregory.
But strikes from Richard Lavery and Samuel Ricketts hauled Telford level and Chris Murphy netted a stoppage time winner for the Conference outfit.
Armstrong opened the scoring early on, catching Telford keeper Chris MacKenzie off his line with a lob from 25 yards out.
Gregory doubled the lead after prodding ball home from close range but Telford improved after the break and pulled a goal back when Lavery headed in Fitzroy Simpson's corner.
Ricketts also found the net with a header and the turnaround was completed by Murphy's dramatic finish from a last-gasp corner.
