Harriers worked their socks off at the Stadium of Light on Saturday but saw their FA Cup adventure come to an end with a 1-0 defeat at Sunderland.
The Stadium of the Capital One Cup finalists was far from full but it was a healthy crowd that greeted the two sets of players including a heaving mass from Worcestershire to back Andy Thorn's men.
Sadly however it would be the home side who drew first blood and it took just five minutes; Sunderland making a rapid start and got their reward when a loose clearance fell to the feet of Charis Mavrias, and he bent it around Danny Lewis
from around ten yards and into the back of the net.
Five later there was almost an equaliser; Michael Gash pouncing on an equally loose ball up at the other end, spinning on it and shooting low at Oscar Ustari who just about managed to dive on it and gather it up.
With 20 on the clock home skipper Lee Cattermole kept Lewis alert with a routine effort from long range while, five minutes later, Gus Poyet's men kept the efforts on goal ticking over as Emanuele Giaccherini planted a shot wide when placed to do much better.
Sunderland began the second half much as they did the second in putting Harriers under some pressure but with some solid defending, Harriers weathered it well and limited El Hadji-Ba to a tame effort that he sent straight into the hands of Lewis.
On the hour mark Lewis parried away a rising drive from Santiago Vergini as Sunderland pressed, Ba unleashing another one from distance a few minutes later that curled just over Lewis's target.
Boss Andy Thorn made a double change midway through the second period as he introduced Callum Gittings
from the bench as well as, making his debut, striker Freddie Ladapo but it was a home sub in Fabio Borini who was wasteful in front of goal just prior as he blazed some way over.
Harriers soaked up pressure for much of the period and restricted to the hosts' further foray's forward to long-range effort but just couldn't manage to wrestle the ball away from them to work out a chance of their own up at the other end.
In the last few minutes they at least managed to do that as they snatched some late counter attacks; Danny Jackman and Lapado both driving off target with Ustari arguably beaten on both occasions.
