Millwall defender Sid Nelson has joined Chesterfield on loan for the rest of the 2017/18 season.
The 22-year-old this week returned to The Den following a similar short-term stint at Yeovil Town, where he made 14 appearances between August and November.
Nelson, who looks set to train with his new Spireites team-mates for the first time on Thursday, joins the League Two side ahead of their game away to Accrington Stanley this weekend.
Everyone at Millwall wishes the centre-back all the best for the coming months.
