Wednesday to travel to The Valley next season
Sheffield Wednesday will have an additional visit to the capital on their calendar next season following the result of the League One play-offs.
Charlton Athletic beat Sunderland 2-1 at Wembley on Sunday, recovering from conceding a calamitous early own-goal to win the game in the last minute of injury time. The Addicks join Luton Town and Barnsley in gaining promotion from the third tier this season.
The play-offs conclude on Monday with the Championship final between Aston Villa and Derby County.
