Leyton Orient and Kidderminster played out an untidy goalless draw in which neither goalkeeper was seriously troubled.

Harriers, who conceded 14 of the 22 free-kicks awarded during a robust first half, also survived a seven-minute spell with 10 men while Scott Stamps was treated for a head injury.

Orient defender Matt Lockwood offered the only serious threat when he forced Stuart Brock into a low save from his free-kick.

Dave McGhee and Carl Hutchings failed to hit the target for the hosts when well-placed early in the second half, while Kidderminster managed their first shot on target in injury-time with keeper Rhys Evans tipping Drewe Broughton's shot around the post.
