Weiss, Florida's first-round draft pick in 2001 and a four-time 20-goal scorer, has produced just one goal and four points in 17 games for the Eastern Conference-worst Panthers.
"He couldn't perform up to his capabilities, in his opinion, and he wanted to get it fixed," Panthers General Manager Dale Tallon said in a report on the team's website.
Weiss, 29, is the longest-tenured member of the Panthers and is scheduled to become an unrestricted free agent during the offseason.
