Kidderminster Harriers have signed three players on youth-loan deals until the end of the season.
He is joined by another Blues youngster, utility man James Fry, 20.
They have also signed left-side player William Boyle, 19, from another Championship side Huddersfield Town.

|Kidderminster Harriers first had dealings with Huddersfield Town when they sold star striker Joe Lolley to the Terriers for a six-figure fee just over a year ago.|
For Kelly and Fry, it is a chance to earn a more permanent contract when their time at Blues comes to an end in the summer.
"Both Birmingham players will be released by the club at the end of the season," said Harriers manager Gary Whild. "It is a good opportunity for them both here.
"With Jordan Tunnicliffe going out to Hednesford Town, and Josh Gowling initially being suspended for us before departing for Grimsby Town, it's left us a little bit short in that area.
"William Boyle is a left-sided player who again can play in different areas. He is very highly thought of at Huddersfield and we are grateful to the club and to manager Chris Powell for allowing him to join us."
