The 41-year-old has secured his first managerial role with the Championship club.
NEWPORT County AFC won't kick-off earlier against Doncaster Rovers in League Two on Saturday because of England’s World Cup quarter-final.
Charlton have sacked manager Ben Garner, the club have confirmed. The south London side have won just five of their 20 matches so far this season, and club owner Thomas Sandgaard said recent form had left the club in a situation where they "had to act". Garner joined Charlton in the summer after steering Swindon into the League Two play-offs last season.
