Midfielder joins Needham on loan.
The U's U21s player will join the Marketmen for a month up to and including November 7th.
Needham are currently plying their trade in the Ryman Premier League following their promotion last season.
Callum will begin his loan spell with a game against Metropolitan Police, as he leaves the U's for his first taste of senior football.
We will be keeping up with his progress here on the official website.
