The Kings also announced Thursday that Rob Blake has been hired as an assistant general manager for the team with which he starred for 14 seasons as its career leader in goals, assists and points by a defenceman.
Brown has played his entire nine-year NHL career with the Kings, helping them win their first Stanley Cup in 2012. He is the team's only American-born captain, a position he's held since October 2008.
Brown has 181 goals, 207 assists and 452 penalty minutes in 641 regular-season games. He was an All-Star in 2009.
Blake spent two stints with the Kings from 1990-2001 and 2006-08, serving as captain for six seasons. He helped lead the team to the Stanley Cup final in 1993; won the club's first Norris Trophy in 1998; won a gold medal with Canada at the 2002 Olympics; and made four of his six All-Star trips as a King.
The 43-year-old Blake will help president and GM Dean Lombardi with contract negotiations and oversee the Kings' top prospects. Blake also will serve as GM for the AHL's Manchester Monarchs.
Blake had spent the last three years in the NHL's player safety department.
