Atieno, 21, turned professional with the Saddlers in July 2004 and had loan spells at Chester and Rochdale.

Harriers boss Stuart Watkiss told the club website: "He's a big lad with tremendous pace and athleticism and has done well in the Walsall reserve side.

"Hopefully he can act as a battering ram of sorts and help break down defences - he'll be a handful."
