MANAGER Mark Yates has warned Kidderminster Harriers to make sure they are not on the receiving end of an FA Trophy upset against Vauxhall Motors on Saturday.

Harriers will be at full strength for the first round tie at Aggborough with captain Stuart Whitehead expected to return after a hamstring injury.

Yates's men go into the game on the back of morale-boosting victories over Gravesend and Altrincham, while Vauxhall have lost their last three Conference North games.

But the Harriers manager has warned against fans and players expecting a repeat of the 5-1 FA Cup scoreline Kidderminster chalked up against Droylsden.

"I've seen them and they're a decent team who are just outside the play-offs in the league below," said Yates.

"They try and play football and they've got some lively forwards and wide players.

"They'll come down, see the place and fancy their chances of raising their game and causing an upset.

"We've got to make sure we are on our game so that we're not on the receiving end of anything."

Whitehead's probable inclusion will mean one of last weekend's winning team making way.

The likely fall guy will be Gavin Hurren, Rob Davies or Jonny Harkness.

If Hurren is dropped, it will be a like-for-like change with Whitehead replacing him in central defence.

Davies's exclusion would see Hurren revert back to a midfield role to accomodate the skipper in defence.

Harkness would be hard done by if he makes way after three free-kick goals and steady defensive displays in the past two games.

But Yates could leave out the Irishman, moving Blackwood to left-back and shuffling his pack in the midfield area.

"Stuart Whitehead is fine now and he's been training all week," said Yates.

"It's amazing that when you win a couple of games that all of a sudden everyone seems to be fit, but that's a good thing when you're coming up to Christmas.

"Stuart is my captain and there is a good chance he'll get back in, but I'm just waiting to see what happens in the next 24 hours.

"Whoever I leave out can consider themselves unfortunate, but I'm not going to say it publicly until I've told the player concerned.

"Yates has fond memories of the FA Trophy, making it to the Wembley final when Harriers lost on penalties to Woking in the mid-nineties.

Assistant boss Neil Howarth won the competition while he was captain of Macclesfield, while Vauxhall Motors boss Carl Macauley lifted the trophy as Burscough skipper.

"Me and Neil have both done well in the FA Trophy before and we're hoping for another good run," said Yates.

"Whether the final is played at Wembley, a Premiership ground or a Championship ground it is still a great incentive for non-league players to do well in this competition.

"Vauxhall Motors chairman Alan Bartlam said his team were playing good football this season despite their recent dip in form.

"In reality the team's playing the best that we ever have done in the Conference North," said Bartlam, who expects around 40 fans to make the trip from Ellesmere Port.

"After a number of years of fighting relegation we've had a fairly good season so far. We're playing good football and we're only seven points off the top.

"Our manager won the FA Trophy when he was captain of Burscough in 2003 so I know he takes this competition very seriously."
