Charlton all but relegated after defeat to Derby County
Charlton are on the verge of being relegated alongside Bolton Wanderers after their latest defeat - at the hands of play-off hopefuls Derby County
A narrow 1-0 defeat leaves Charlton second bottom of the table, 11 points adrift of safety with only four games remaining this season.
Derby remain fifth, nine points ahead of Cardiff City, who are just outside the play-off places in seventh.
Jose Riga's side matched the Rams for long periods, but their hard work was undone as they conceded a league-high 25th set-piece goal, Russell heading in after they failed to clear Ince's corner.
The goal came moments after Teixeira appeared to have given the Addicks the lead, only for his effort to be ruled out for a foul on Derby keeper Scott Carson.
Charlton's Simon Makienok missed a late header as Darren Wassall's Derby held on.
With Rotherham gaining a point at home to Nottingham Forest - MK Dons who drew at Preston look most likley to be the third team to face the drop after just one season at this level.
