Kansas City, Kan. ? Kansas City Wizards president Robb Heineman is telling supporters on the team’s Web site that the Wizards will be moving to Kansas.

In a letter posted on the Web site Thursday night, Heineman says he is confident STAR bonds can be sold for the construction of a soccer stadium in Wyandotte County’s Village West development.

He says site preparation could begin as early as next week, with plans to have the stadium open midway through the 2011 season.

Kansas City, Mo.-based Cerner Corp. and OnGoal, the group representing the Wizards, are proposing a $414 million development near NASCAR’s Kansas Speedway in Kansas City, Kan. The project includes an office complex for 4,500 Cerner employees, an 18,500-seat stadium for the Wizards and two dozen soccer fields for amateur teams.
