Brentford and Bradford City will need a second match to decide who will play in the FA Cup with Budweiser Third Round.
The teams will replay at Griffin Park in a match provisionally scheduled on Tuesday December 18 after they drew 1-1 in West Yorkshire.
Brentford went ahead when Clayton Donaldson scored late in the first half but Bradford came back in to it after making a triple change on the hour mark.
The home side equalised inside the final 20 minutes and both teams had chances to win it but will have to do it all again next month.
The home side started brightly and had the territorial advantage in the first ten minutes.
The Bantams have not lost a cup game all season, reaching the Quarter Finals of the Capital One Cup and mounting an assault on the Johnstone’s Paint Trophy.
They looked like a team with no fear of higher level opposition and used their strengths, particularly the height of striker James Hanson, to good effect.
Hanson had an early shot blocked before Alan Connell fired a free kick well and then had a shot blocked after a quick break.
Brentford were pressed hard early on and were unable to put a series of passes together but slowly got a grip on things as the minutes ticked by.
An Adam Forshaw shot, deflected in to the arms of Bradford goalkeeper Matt Duke, was their first sight of goal and the midfield player was at the heart of most of Brentford’s attacking moves.
The Bees made a tactical switch midway through the half, moving Donaldson from the right side to partner Paul Hayes in attack and although they did not create much, they had a measure of control of the ball.
The almost scored in bizarre fashion when Curtis Good sliced a Donaldson cross and Duke had to turn it over the crossbar.
The Bradford goalkeeper was truly tested by Harry Forrester later in the half, the midfield man fired in a shot from 25 yards that Duke had to turn away at full stretch.
The goalkeeper was helpless, however, when Brentford went ahead just before half time.
Hayes and Forshaw combined on the right and the ball ricocheted in to the path of Donaldson when Good went in to make a tackle – the striker fired a low shot past Duke’s right hand and in to the bottom corner.
Hayes had a header saved soon after but Bradford tried to respond before the break and Hayes had to be alert at the other end to divert a Hanson header wide of his own past.
The Bees went in at half time ahead and came out strongly after the break as they attempted to seal the game.
Donaldson headed a Sam Saunders corner inches wide and was then denied by a superb reaction save from Duke after a nice turn in the box.
Forrester also shot over for The Bees while Bradford struggled to stay in the game.
Rory McArdle shot over for the home side when a corner was half cleared but a triple substitution on the hour mark gave them impetus.
Nahki Wells, one of the trio, missed the target when he could have scored with his first touch and then turned a Blair Turgott cross wide.
He went close again soon after with a low shot that Lee got down well to keep out while Saunders went close at the other end.
Bradford had the momentum and got the equaliser with 19 minutes remaining.
A cross from the left bounced around the penalty area and Hanson reacted quickest to fire home from 15 yards.
The home side’s direct play was giving them openings – Gary Jones shot narrowly over when one long ball was half cleared and when the next was played over the top, Hanson lashed a shot off target.
They came within a whisker of going ahead when Hanson nodded on and Wells got in behind, his shot hit the post and Shaleum Logan made a remarkable to tackle to prevent him putting the loose ball home.
The game became stretched as both teams tried to win it at the first attempt.
Donaldson missed the target when well placed before Logan forced Duke to save low and Harlee Dean headed wide.
A Wells free kick was blocked and Good headed wide late on but neither team could find a winner and the tie will be settled at Griffin Park.
