"Doc is a fantastic coach and leader and I am thrilled he is coming back for the upcoming season," Celtics co-owner Steve Pagliuca said Wednesday in an e-mail to The Associated Press.
Rivers said in a text message to The Boston Globe, "I want another crack at it with this group."
Rivers' decision does not mean that the nucleus of the Celtics team that won the franchise's unprecedented 17th NBA title in 2008 will be back for a run in 2010-11. Paul Pierce reportedly has said he will opt out of his contract and become a free agent, and Ray Allen is also due to become a free agent on Thursday.
Rivers has a career coaching record of 451-380, including 280-212 with the Celtics.
Stoudemire opts out
Amar'e Stoudemire has opted out of the final year of his contract with the Phoenix Suns.
