youth academy and had a loan spell as a youth with Aylesbury.

Lambert said "He's a quality player who has played Premier
League football as well as having solid experience at Championship
level, so I'm delighted we've been able to bring him in. "He's
here until January so he will provide competition for places when
Michael and Zak Whitbread are fit
again, which I think you've got to have."
