via rotoworldDetroitLions.com mentions C Dominic Raiola and RG Stephen Peterman as candidates for offseason release.
Raiola, 34, and Peterman, 31, are both entering the final years of their respective contracts and will collectively count $9 million against the salary cap. Detroit's 2013 money issues have been well-documented. The Lions could conceivably have four new starters along the offensive front, and the team's official website names Riley Reiff, Bill Nagy, and Jason Fox as potential replacements.
Looks like Raoiola and Peterman may be gone...
