Lecavalier has been a healthy scratch for most of the season, registering just one assist in seven games this season. The veteran has three years remaining on his contract with an annual salary cap hit of $4.5 million. However, the 35-year-old is set to forgo the final two years of his deal and retire at the end of the 2015-16 season.
The longtime captain of the Lightning joined the Flyers in July 2013 after being bought out by Tampa Bay. In 1,170 career regular-season games, the first-overall pick from 1998 has 411 goals, 521 assists and 828 penalty minutes.
Schenn has five points and 30 penalty minutes in 29 games with the Flyers this season. The 26-year-old has a cap hit of $3.6 million and is set to become an unrestricted free agent in the summer. Schenn was originally acquired by the Flyers in 2012 from the Toronto Maple Leafs in exchange for James van Riemsdyk. The Saskatoon native joins a Kings franchise that drafted his brother and now-former Flyers teammate, Brayden, back in 2009.
Weal, 23, was drafted 70th overall by the Kings in 2010 and has played just 10 games in the NHL.
In order to make room on its roster for Lecavalier and Schenn, the Kings have also assigned blueliner Derek Forbort to the Ontario Reign of the AHL.
