Harriers made a double swoop this week by securing the signatures of defender Mike Williams and striker Lee Morris.
The duo have both agreed to sign one-year deals to bolster Harriers' squad.
They both played in Harriers' 1-0 friendly win over Chasetown.
While Williams had been at Harriers all pre-season, Morris had been on trial at Bradford City.
However, he looked lively on his debut against the Scholars.
Morris, who had been released by Hereford in April, has struggled to nail down a regular starting place over the last few years.
Derby County signed him for £3,120,000 from Sheffield United in 1999 and scored 17 goals in 92 league appearances.
Williams, 23, was released by Wrexham at the end of last season after five years there but had looked solid on the left side of defence.
Harriers boss Steve Burr said: "I have been really impressed with what I have seen from Mike."
"Although he is still at a young age he is a relatively old head - there aren't many players who have played as many games at this stage as he has, in the Football League and in the Conference.
"He will be a very valuable addition to the squad."
Midfielder Nathan Hayward has left Harriers. He had been offered a new deal but has been allowed to move on after failing to agree personal terms.
