The Addicks have shored up their injury hit defence with a one month loan of Danny Seaborne from Southampton: Seaborne
He can play at centre back or left back. Presumably he will slot in at left back allowing Solly to revert to being right back.
Millwall tried to sign him on loan last month, but Southampton wanted his wages paid in full: Millwall
I have now found his Wikipedia entry: Seaborne . He hails from Barnstaple in deepest Devon and was taken on as a trainee by Exeter, but was then loaned out to various teams such as Clyst Rovers. He also suffered a broken leg in a game against Bodmin, but interestingly eventually formed an effective defensive partnership with Matt Taylor.
