Leeds Rugby have announced they will begin the �7m redevelopment of their Headingley Stadium next month. Work on the ground, which is home to Leeds Rhinos and Tykes, will begin on 11 October and is expected to be completed by the end of July 2006.
Ground capacity will be reduced by nearly 5,000 to 16,600 while work on the new Carnegie Stand is carried out.
It has been financed, without any grant funding, in partnership with Leeds Metropolitan University.
Leeds Rugby chief executive Gary Hetherington said: "This is an historic announcement for the stadium and shows our commitment to restoring Headingley to its correct place at the pinnacle of rugby stadia.
"We are now in a position whereby Leeds Rhinos are world champions and Leeds Tykes have an opportunity to be Heineken Cup champions this season and we are investing the profit into Headingley Stadium."
