Burr is well aware he needs to bring in another centre back after Tom Marshall turned down a new deal.
With Luke Jones joining big-spending Mansfield Town last week, Harriers are in need of extra bodies to provide competition for Mike Williams and 20-year-old Cheyenne Dunkley, the club’s only recognised central defenders.
However, Burr admitted he will have to be patient.
He said: “We’ve lost two centre-halves in the space of a week so my priority is in that department.
“We have spoken to a few people but at the moment we’re miles away from sorting anything out.
“Things can be slow this time of year, a lot of players are on holiday or waiting to see what deals are out there.
“There’s no hard feelings about the players moving on, we wish them the best of luck.
“We’ve already brought in Cheyenne [Dunkley] who is a young lad we think can improve and we’re really pleased to have him at the club.”
Marshall has yet to sign for a club but has informed Harriers he will not be returning and is mulling over several offers.
He is rumoured to be interesting AFC Telford and at least one other Blue Square Bet Premier outfit from outside of the Midlands.
Meanwhile, Nick Wright’s departure from the Aggborough outfit was confirmed when he joined Mansfield Town. Wright was top-scorer with 17 goals for Harriers but opted to sign for the Stags instead of a new deal at Kidderminster.
Meanwhile, chairman Mark Serrell said the club have spoken to Worcester City about playing at Aggborough while their new ground is being built.
Serrell has had a meeting with City’s company secretary John Jordan over the plans, which start in the 2013-14 season.
He is set to talk with Worcester officials in the next week.
City are moving from their traditional base on St George’s Lane at the end of the next campaign and will need a new home while the new stadium at Nunnery Way is built.
Worcester have also sounded out Bromsgrove Sporting about playing at the Victoria Ground.
“I’ve had one meeting with John Jordan at Worcester which went well,” said Serrell.
“We’ve drawn up an offer for ground sharing but nothing has been agreed yet.
“Primarily this will be about helping our neighbours out.
“Any funds we make from the deal will be put back into the pitch, which is will obviously used quite a bit.”
