SPARTANBURG, S.C. -- The Carolina Panthers have waived tackle Charles Spencer for what coach John Fox calls a "conditioning issue."

The Panthers claimed Spencer off waivers from Houston two days before players reported to training camp. The former third-round pick hasn't played in the NFL since breaking his leg during his rookie season in 2006.

Spencer had missed several practices for what the team called a sore knee, but Fox said Thursday he was let go because of "conditioning and weight."

The Panthers did not immediately replace Spencer on the 80-man roster. Fox said he wasn't sure if they'd sign a player before Saturday's preseason opener against Indianapolis.
