The 19-year-old left-back joined the high-flying Skrill Premier club on a youth loan in the summer and was due to remain until January.
He made a total of 19 league starts during the stint, the latest of which came in Saturday's 1-0 victory at Hereford.
But Blues boss Lee Clark has been forced to recall the talented youngster after Mitch Hancox sustained a knee injury in the latter stages of Birmingham's 2-2 draw against Middlesbrough in the Championship on Saturday.
Hancox was replaced in injury time by Kyle Bartley, who duly headed home a last-gasp leveller, and is currently awaiting news on the extent of the problem.
It is the second time Bell has been recalled to St Andrew's this season, with the teenager returning in late September only to be allowed to go back to Nuneaton a week later.
