Sam Cassell will leave the Washington Wizards to take an assistant coaching position with the Los Angeles Clippers.
Cassell became an assistant with the Wizards in 2009.
A reunion with Rivers has been rumored for several weeks, with the Clippers losing assistants Tyronn Lue (to Cleveland) and Alvin Gentry (to Golden State) this offseason.
Cassell will receive a significant pay raise though it will be a lateral move.
Cassell played for the Clippers during his playing career.
