Charlton are keeping tabs on Rangers defender Lee Hodson.
The former Watford man signed a three-year deal with Rangers last summer, but has made just 11 league appearances this season.
Addicks chief Karl Robinson bossed Hodson, 25, at MK Dons and SunSport says he is keen on a reunion.
He played 40 times during his three-year spell under Robinson, scoring twice.
Hodson is known for his defensive flexibility, and can play as either a right or left full-back.
Charlton are in desperate need of left-backs following Adam Chicksen’s release and Lewis Page’s hamstring injury.
And Hodson could be a welcome addition to Robinson’s team, who will look to mount a promotion push next term.
