Lombardi said he won't buy out Brown, who has six years remaining on a eight-year contract worth $47 million, according to GeneralFanager.com. Lombardi said he met with Brown a month ago, and Brown subsequently met with Kings coach Darryl Sutter "on what he needs to do and what his role is."
Lombardi said he believes Brown can get back to being the effective player he was earlier in his career.
"He perfectly recognizes that for us to be successful as a team, he needs to get back to where he's capable," Lombardi said.
"Despite [that] he hasn't produced at the level he's capable [of], it wasn't because of effort. He puts enormous pressure on himself … one time not too long ago, he was one of the best power forwards in the League. That's where he needs to be."
Brown is expected to speak about the change later this month.
Lombardi and Kopitar spoke about the Kings' disappointing seasons since the '14 Cup win. They missed the playoffs last season and were eliminated in the first round by the San Jose Sharks in five games this postseason.
"Our top guys, we didn't perform to our potential," Kopitar said. "….to have that [leadership] change, I'm sure it has nothing to do with [Brown]. It's the organization trying to find something and give him a break and take some off his shoulders so he can find his game again."
Lombardi said attempts to re-sign left wing Milan Lucic have been slowed but "it's probably safe to say we will be making our best effort under the circumstances probably early next week."
"There's no question we want him back, and he clearly wants to be back, but there's a number of things we've had to work through," Lombardi said.
