The Carolina Panthers have waived defensive tackle 
In his fourth NFL season, Leonard was acquired by the Panthers in a trade with the Cleveland Browns during the 2009 preseason in exchange for a 2010 sixth-round draft choice. He played in two games with one start last year and posted 11 tackles and one sack before suffering a fractured left ankle on Carolina's final defensive play at Atlanta in Week 2 and being placed on injured reserve.
The Panthers did not immediately replace Leonard, meaning they have an open spot on the 53-man roster.
