Kidderminster have signed defender Sam Smith ahead of Wednesday's trip to Edgar Street.
The 24 year old comes in on non-contract terms after four years with Stourbridge and previous experience with Chasetown. His arrival comes with former Bulls loanee Josh Gowling doubtful for the trip after having to be subbed during their win over Dartford on Saturday.
The other former Bull in the Harriers' ranks, forward Steve Guinan, is also unlikely to feature on Boxing Day. The much travelled frontman, who turns 37 today, has made only a handful of sub appearances this season - the last of which was a single minute at the start of December.
The Bulls have two former Harriers players in their current ranks. Brian Smikle spent four years at Aggborough before following Mark Yates to Cheltenham, while James McQuilkin was loaned by the Bulls to the Harriers back in January.
