Panthers signed DT Colin Cole.
Cole, an eight-year veteran, was last heard from in July of 2011 when he was battling ankle issues. The run-stuffing defensive tackle has 218 career tackles and 4.5 sacks. He was last with the Seahawks, starting 26 games from 2009-10. Carolina is annually in search of space eaters, so Cole -- last listed at 6-foot-2, 328 -- is worth a look. He’s going on 33, but should be fresh after the 2012 layoff.
