Rushden & Diamonds have signed versatile Millwall youngster Michael Bostwick on a free transfer.
Bostwick, who can play in midfield or defence, has signed an 18-month contract with the Conference club.
He had not played for the Lions' first team, but has Conference experience from two loan spells at Crawley, for whom he has made 32 appearances.
Boss Graham Westley could hand Bostwick his debut in Monday's Conference game at high-flying Oxford.
